if you had to explain to someone the difference between heat and temperature, how could you use one of the following to demonstr

Rainbow [258]

Answer:

We associate paper money or points in video games, as molecules that make a heat transfer or an increasin in its temperature.

Explanation:

The meaning of heat is associated with an energy transfer, where for example if we put a spoon in a cup of hot drink, the drink will be transferring heat to the spoon. It is a transfer of energy between two bodies due to a difference between their temperatures.

Temperature is associated with the movement of kinetic energy of the molecules. When the temperature is higher, the kinetic energy is higher, so as more detained they are, temperature will be lower.

If we take paper money as molecules, the greater movement of money explains that we have an increase in temperature (we would be hot), even if we think of video games, for example gambling where as more points we gain, we generate an increase in the movement of "molecules".

When we use paper money to buy something we are doing a heat transfer.

We can associate terms to the Thermodynamic where

Heat = Internal energy + work

For clearance would be

Internal energy = Heat - Work

The money we use less the work we do keeps our internal energy. If in a gambling video game, we earn points over and over again, when withdrawing the prize we perform "heat transfer".

88.5 mol of P4O10 contains how many moles of P?

Dennis_Churaev [7]

Looking at the formula, each mol of P4O10 contains 4 mol of P, so
(58.5 mol P4O10) x (4 mol P/ 1 mol P4O10) = 234 mol

What is the energy of a 4.66 x 1014 Hz wave?

docker41 [41]

I attached the working and the answer to both questions below.

Please note that E = energy, ν = frequency, h = Plank's Constant

The energy of a 4.66 x 10¹⁴ Hz wave is 3.088 × 10⁻¹⁷ J
