Answer:

Explanation:

Heat moves from hot sand to the bottoms of your feet by conduction. Conduction is the transfer of heat between objects that touch each other.

Heat moves from hot sand to the bottoms of your feet by conduction.Hence Option (A) is correct.

Heat conduction is a phenomenon that occurs through the interaction of neighbouring atoms and molecules, transferring their energy/heat (partially) to their neighbours.

This is the most significant means of heat transfer within a solid and between solid objects in thermal contact.

Conduction is the transfer of heat between objects that touch each other.

Therefore, Heat moves from hot sand to the bottoms of your feet by conduction.Hence Option (A) is correct.

Explanation:

Plants rely directly on the energy from the sun. The chloroplast create glucose from the sun rays through a process known as photosynthesis. Mushrooms, on the other hand, do not have the ability to use the sun's rays to create food, so they instead gather their energy from the nutrients from the soil or decaying things, such as plants, that once used the sun's radiation as sustenance. So basically mushrooms use the radiant energy from the sun indirectly and plants use it directly

Answer:

Ionization Energy is defined as the energy required to remove the most loosely bonded atom from an atom in its gas phase. Ionization energy in metals decreases from top to bottom and from right to left and on the periodic table.

Metals have lower ionization energies that help metal atoms to lose electrons to nonmetal atoms easily. The metallic character of a metal increases as ionization energy decreases, it means reactivity of metals increases with decreases in ionization energy.

Hence, the reactivity of metals increases with low ionization energies..

The metals tend to have high reactivity due to low ionization energy.

The ionization energy can be defined as the energy required to remove the atom from metal in its gaseous state. The metals on the left side of the periodic table have loosely bonded electrons, requiring less ionization energy for the removal of an electron. Thus on moving from left to right in a periodic table, the ionization energy increases.

On moving from top to bottom in a periodic table, due to steric hindrance, the electrons are loosely bonded and require less energy for the removal of electrons. Thus on moving down the group, the ionization energy decreases.

The low ionization energy shows that there is easy removal of electrons tends to increase its reactivity.

Thus, low ionization energy results in the high reactivity of metals.

Explanation:

Protein denaturation is what makes eggs solidify, collagen break down and convert to gelatin in slow-cooked meat, fish and chicken become more opaque, and all meats firm up and change color. This is primarily achieved by applying heat, but can also occur in the presence of acidic and basic ingredients.

The Maillard reaction is the primary effect taking place in “browning”, and produces more flavor compounds, resulting in more complex flavors in food that we generally find enjoyable. It involves reaction between amino acids (proteins) and a certain class of sugars called reducing sugars — mostly the monosaccharides, such as glucose and fructose.

Caramelization is a secondary browning effect that occurs in foods with sugar content, even though all browning is often referred to as “caramelizing”. It mostly takes place at higher temperatures than Maillard reaction (with the notable exception of fructose).

Pyrolysis, or thermal decomposition (chemical breakdown) begins at higher temperatures. While caramelization is technically in this category, the main effect of this reaction is carbonization. This is what we generally mean when we talk about “burning” food, even though no combustion has taken place. It’s also what happens when we cause oil to smoke and darken. In small, controlled amounts, this can still provide desirable flavors, such as char on the outside of meat and contributing to “wok hei” in stir frying — the latter of which does involve some combustion.

Acid-base reactions produce carbon dioxide, which creates the rise in quick breads such as biscuits. These often occur at room temperature, but some also don’t occur until higher temperatures — which is how “double-acting” baking powder works.

Gluten formation occurs when you mix flour and water, resulting in stretchy doughs and fluffy baked goods. This occurs easily at room temperature.

Given parameters:

Distance of ATV  = 60miles

Time = 2hrs

Unknown:

Speed  = ?

Solution:

Speed is a scalar quantity. It has magnitude but no direction. Mathematically, speed is distance divided by time.

                      Speed  = [tex]\frac{distance}{time}[/tex]

 Input the parameters;

              Speed  = [tex]\frac{60}{2}[/tex]  = 30miles/hr

The speed of the ATV is 30miles/hr

Answer: Neutrons

Explanation:

Isotopes are atoms of the same element that have different numbers of neutrons but the same number of protons and electrons. The difference in the number of neutrons between the various isotopes of an element means that the various isotopes have different masses.

Answer:

neutrons

Explanation:

isotopes has the same proton number but different nucleon number because there's different numbers of neutrons in isotopes

Answer:

a copper pipe can't simply be welded directly to a lead pipe because lead has a far lower melting point than copper and thus the lead will melt before the copper can even be effected.

Explanation:

A lead pipe is a pipe that's made of lead and is usually used in distribution of potable water to connect a water main source to a user's preferred area.

Now, a copper pipe can't simply be welded directly to a lead pipe because lead has a far lower melting point than copper and thus the lead will melt before the copper can even be effected.

Lead has a melting point of 327.5° C while copper wire has a melting point of 1082.778 °C

Answer:

Explanation:

The average speed can be found by using the formula

[tex]v = \frac{d}{t} \\ [/tex]

where

d is the distance

t is the time taken

So we have

[tex]a = \frac{24}{2} \\ [/tex]
