Heat Calculations

What are the three variables that affect heat according to the passage?

• Mass, temperature, and specific heat capacity

• Volume, pressure, and density

• Color, texture, and shape

• Time, speed, and distance

Which of the following best explains why water has a higher specific heat capacity than air?

• Water can hold more heat than air

• Water is denser than air

• Water is a liquid and air is a gas

• Water has a higher boiling point than air

If you have two pots of water at the same temperature, which factor will determine which pot has more heat?

What is the formula used to calculate heat?

• Q = m (ΔT) (C)

• Q = m + ΔT + C

• Q = m / (ΔT) / C

• Q = m * ΔT + C
