Contrast the three types of heat transfer
Answer:
There are three modes of heat transfer.
1. Conduction
2. Convection
3. Radiation
1. Conduction: Heat transfer through the process of conduction occurs in substances which are in direct contact with each other. It generally takes place in solids.
For example: When frying vegetables in a pan. Heat transfer takes place from flame to the pan and then to the vegetables.
2. Convection: In this process, heat is transferred in the liquid and gases from a region of higher temperature to a region of lower temperature. Convection heat transfer occurs partly due to the actual movement of molecules or due to the mass transfer.
For example: Heating of milk in a pan.
3. Radiation : It is the process in which heat is transferred from one body to another body without involving the molecules of the medium. Radiation heat transfer does not depend on the medium.
For example: In a microwave, the substances are heated directly without any heating medium.

Which answer best explains the choice of materials used in this coffee
maker?
A. Plastic is used for the handle to slow the transfer of thermal
energy, because its electrons do not move freely.
B. Metal is used for the burner below the pot to speed the transfer of
thermal energy, because its electrons do not move freely.
c. Metal is used for the burner below the pot to slow the transfer of
thermal energy, because its electrons move freely.
D. Plastic is used for the handle to speed the transfer of thermal
energy, because its electrons do not move freely.
The best explains the choice of materials used in this coffee maker is metal is used for the burner below the pot to speed the transfer of thermal energy, because its electrons do not move freely.
What is used to make coffee?As an example, we can mention thermoses, scales, bottles and even special bottles.

6. Which of the following processes puts excess carbon in the environment? (1 point)
a. Marine respiration
b. Burning fossil fuels
c. Terrestrial photosynthesis
d. Nitrification
n this experiment the bag contains a hypertonic solution (sucrose), while the beaker only contains water. If you leave the bag inside of the beaker for approximately 45 minutes; the movement of water will occur from the ________ to the _________.
The water will move from beaker to the bag of sucrose due to concentration difference.
In which direction the water will move?The movement of water will occur from the beaker to the bag because the concentration of water is lower in the bag and higher in the beaker. So due to the process of diffusion, the water will move from the higher concentration region to lower concentration region.
So we can conclude that the water will move from beaker to the bag of sucrose due to concentration difference.

Predict what would happen to other organisms in an ecosystem in which all the decomposers went extinct?
Answer:
the other organism when they died with would not able to be decompose the they dead bodies would be left to rot . And then they food cycle would not be able to grow .In short food chain would disssolve
Explanation:
When organisms die, decomposers break down the dead bodies and the nitrogen is released and another type of bacteria breaks it down into gaseous nitrogen. Without decomposers and other types of bacteria, the nitrogen cycle would not be maintained. Plants would die off and the food chain would dissolve. As plant are primary producers

1. A 42,000 kg train car travelling at 10 m/s toward a stationary train car with a mass of 40,000 kg. After collision, the two sticked and moved together with the same speed. Solve for the final speed of the combined object after collision and identify their direction.
Given,
A 42,000 kg train car travelling at 10 m/s toward a stationary train car with a mass of 40,000 kg.
What is momentum?Momentum is a product of the mass of a particle and its velocity. Momentum is a vector quantity which means it has both magnitude and direction. Its formula = mass × velocity.
Solve for momentum:
M= (42,000kg)(40,000kg) / (10m/s)
M = 42,000 kilograms - 40,000 kilograms
M = 2,000kg
M = 2,000 kg ÷ 10m/s
= 200m/s
-Thus they collison at the same speed of 200m/s.

Cortisol (hydrocortisone) is a ______ that affects glucose, protein, and fat metabolism and is produced in the ______ zone of the adrenal cortex.
Cortisol (hydrocortisone) is a steroid that affects glucose, protein, and fat metabolism and is produced in the middle zone of the adrenal cortex.
What is cortisol?Cortisol or hydrocortisone is a steroid hormone, produced by the adrenal cortex, that regulates the metabolism of carbohydrates and maintains blood pressure.
The adrenal gland is responsible for the secretion of the hydrocortisone hormone; specifically the middle part of the adrenal gland also called the zona fasciculata.
Therefore, cortisol (hydrocortisone) is a steroid that affects glucose, protein, and fat metabolism and is produced in the middle zone of the adrenal cortex.
