How much heat energy (Q) moves from 20 g of water when its temperature changes from 25°C to 20°C?

Back

418 Joules

Front

What is the formula to calculate heat energy (Q)?

Back

Q = m * c * ΔT, where m is mass, c is specific heat, and ΔT is the change in temperature.

What is the relationship between pressure and volume in a gas at constant temperature?

Back

Boyle's Law: P1 * V1 = P2 * V2.
