Thermodynamic Diagnostic Flashcard

Front

What is the specific heat capacity of water?

Back

4.18 J/g°C

Front

How do you calculate the final temperature of a substance when energy is added?

Back

Use the formula Q = mCpΔT, where Q is the energy added, m is the mass, Cp is the specific heat capacity, and ΔT is the change in temperature.

Front

What is the formula for calculating heat energy (Q) in a substance?

Back

Q = mCpΔT

Front

What does an endothermic reaction do with heat energy?

Back

An endothermic reaction takes in heat energy.

Front

What is the final temperature of 6.20 g of water at 18.0 °C after adding 980. J of energy?

Back

55.8 °C

Front

Which material typically has the highest specific heat capacity?

Back

Water

Front

What happens to the temperature of a substance during an endothermic process?

Back

The temperature of the substance decreases as it absorbs heat.

Front

What is absolute zero in Kelvin?

Back

0 K

Front

What is the significance of specific heat capacity in thermodynamics?

Back

Specific heat capacity determines how much energy is required to change the temperature of a substance.

Front

What is the relationship between mass, specific heat capacity, and temperature change in thermodynamics?

Back

The relationship is defined by the equation Q = mCpΔT.
