What does the specific heat capacity of a substance indicate?

• The amount of heat to raise the temperature of 1g by 1°C

• The maximum heat a substance can absorb

• The temperature increase per joule of energy

• The energy needed to melt a substance

What is the formula for calculating heat capacity?

• Q = m * c * ΔT

• Q = m - c * ΔT

• Q = m / c * ΔT

• Q = m + c + ΔT

In the heat capacity equation, what does 'm' stand for?

• Maximum capacity

• Mass of the substance

• Momentum of the object

• Measurement error

What does the ΔT represent in the heat capacity formula?

• Total temperature

• Threshold temperature

• Change in temperature

• Temperature under test

What unit is used to measure specific heat capacity in the given example?

• Joules per gram

• Kelvin per kilogram

• Calories per gram degree Celsius

• Joules per kilogram degree Celsius

How is the change in thermal energy calculated in the example?

• By dividing the heat by the change in temperature

• By multiplying the mass and specific heat by the change in temperature

• By adding the initial and final temperatures

• By subtracting the initial temperature from the final temperature
