Look at the map of temperature versus latitude
globe. Why are the bands not straight
around
the
across!
The bands not straight around since location is not a factor in measuring temperature. Temperature seems to be not the same as the power of a thermodynamic process.
What is temperature?Temperature is a unit used to describe hotness or coldness. It may be stated in terms of any number of arbitrary scales and shows the direction in which heat energy would naturally flow, i.e., from a hotter body to a region of lower temperature (one at a lower temperature).
Temperature seems to be not the same as the power of a thermodynamic process; for instance, an iceberg has a significantly larger total heat energy than a match, despite the fact that a match is burning at a substantially higher temperature. The bands not straight around since location is not a factor in measuring temperature.
Therefore, the bands not straight around since location is not a factor in measuring temperature.

What is the wavelength, in meters, of yellow light with a frequency of 5.10 x 1014 Hz?
Answer:
5.88 × 10⁻⁷ m
Explanation:
Speed of Light = Wavelength times Frequency
c = λν
Step 1: Define
c = 3.0 × 10⁸ m/s
ν = 5.10 × 10¹⁴ Hz
λ = unknown
Step 2: Solve for λ
3.0 × 10⁸ m/s = 5.10 × 10¹⁴ Hz · λ
λ = 5.88235 × 10⁻⁷ m
Step 3: Simplify
We are given 3 sig figs.
5.88235 × 10⁻⁷ m ≈ 5.88 × 10⁻⁷ m

Explanation:
The sun's energy influences climate in different ways. For example, the latitudes at the equator receive more intense energy from the sun and therefore have warmer temperatures. How does the sun's energy MOST DIRECTLY influence precipitation in an area?
Answer:
The Sun's energy is transferred as both light and heat energy, that raises the temperature of an area receiving the Sunlight. The increased temperature results in the evaporation of water from surfaces and water bodies, such that the mass of water vapor rises up into the atmosphere and condenses when it gets away from the ground heat to the cooler and higher altitudes
When there is a situation of low pressure, the wind blows into the low pressure, where, in the equator, comprises of high temperature air which could contain considerable amount of vapor from the neighboring water bodies, resulting in the eventual rise of very moist air, up into the atmosphere, that condenses at low temperature at the high altitudes, accumulate into larger masses of liquid water, and fall as rain

Explanation:
Explain whether the formula CuO can be used to represent both Copper oxide(1) and Copper(2) Oxide
Answer:
See explanation
Explanation:
Oxide has a 2- charge.
Copper (I) Oxide = Cu2O
Copper (II) Oxide = CuO
The formula CuO can not be used to represent both copper I oxide and copper II oxide.
The formula of an ionic compound takes into account the oxidation state and valency of the the metal cation which is usually shown as a Roman numeral in the name of the compound.
For the compound copper I oxide, the correct representation of the compound is Cu2O. This shows that oxygen has a valency of 2 while copper has a valency of 1 in the compound.
The correct representation of copper II oxide is CuO. In the compound, both copper and oxygen have valency of 2.

Joyce poured 200 milliliters (mL) of water into a beaker, placed a thermometer in it, and heated it until it started to boil. She recorded a temperature of 100 degrees Celsius (°C) when it started to boil. She repeated the process with 400 mL of water. What would be the temperature when this second sample started to boil?
Answer:
473 °C
Explanation:
The following data were obtained from the question:
Initial volume (V1) = 200 mL
Initial temperature (T1) = 100 °C
Final volume (V2) = 400 mL
Final temperature (T2) =..?
Next, we shall convert celsius temperature to Kelvin temperature. This can be obtained as follow:
T(K) = T (°C) + 273
Initial temperature (T1) = 100 °C
Initial temperature (T1) = 100 °C + 273 = 373 K
Next, we shall determine the final temperature of the water as follow:
Initial volume (V1) = 200 mL
Initial temperature (T1) = 373 K
Final volume (V2) = 400 mL
Final temperature (T2) =..?
V1/T1 = V2/T2
200/373 = 400/T2
Cross multiply
200 × T2 = 373 × 400
200 × T2 = 149200
Divide both side by 200
T2 = 149200/200
T2 = 746 K
Finally, we shall convert 746 K to celsius temperature. This is illustrated below:
T(°C) = T(K) – 273
T(K) = 746 K
T(°C) = 746 – 273
T(°C) = 473 °C
Therefore, the temperature of the second sample when it starts to boil is 473 °C
