Thermodynamics Quiz

According to the first law of thermodynamics, what is the relationship between the change in internal energy of a system and the heat and work done on the system?

• Change in internal energy = Heat added / Work done

• Change in internal energy = Heat added + Work done

• Change in internal energy = Heat added - Work done

• Change in internal energy = Heat added * Work done

• third law of thermodynamics

• second law of thermodynamics

• zeroth law of thermodynamics

• first law of thermodynamics

• calorie (cal)

• newton (N)

• watt (W)

• joule (J)

Which type of heat transfer occurs through direct contact between two objects?

• Convection

• Conduction

• Radiation

What is the process called when heat is transferred through the movement of fluids, such as air or water?

• conduction

• convection

• radiation

• evaporation

According to the second law of thermodynamics, what is the direction of heat flow between two objects at different temperatures?

• Heat flows from hot to cold.

• Heat flows randomly between the two objects.

• Heat flows in both directions simultaneously.

• Heat flows from cold to hot.

What is the specific heat capacity of a substance?

• The specific heat capacity of a substance is the amount of heat energy required to raise the temperature of one unit mass of the substance by one degree Celsius.

• The specific heat capacity of a substance is the amount of heat energy required to raise the temperature of one unit volume of the substance by one degree Celsius.
