As refrigerant passes through the expansion valve, it cools down or heats up?

Chemistry

Answer:

It cools down

Explanation:

The expansion valve lowers down the pressure of the refrigerant (in liquid form). This allows the refrigerant to expand. As the refrigerant expands the heated molecules in it get spread to a larger area and thus the oscillatory vibrations in the molecules get reduced there by reducing the kinetic energy ( KE )and thus the heat. Also sometimes spray of Aerosols are used to cool down the refrigerant.

Answer: Combustion changes the potential chemical energy into kinetic energy in the form of heat. For combustion an organic wood combines with oxygen already in the air and undergoes a chemical reaction that gives off carbon dioxide,water,and energy in the form of heat and light.

Convert 0.00200 g into Mg and answer in scientific notation:
Masja [62]

Answer: 2.00x10^{2}

Explanation: 1 gram is equal to 1000 Milligrams so

0.00200g=\frac{1000mg}{1g}

Since you go straight across its just multiplication so 0.00200x1000=200mg

To answer it in scientific notation it should just be 2.00x10^{2} mg
