Select the correct answer from each drop-down menu. a steel plaque is attached to a block of wood. the steel and the wood have the same mass. after the steel plaque and the wooden block were left outside in the sun for a period of time, both the steel and the wood had increased in temperature, but the steel had a higher temperature than the wood. it’s possible that the steel plaque had a higher temperature than the wooden block because it its surroundings. if the steel and the wood received the same amount of energy from the sun, then the specific heat capacity of the steel must be the specific heat capacity of the wood. 1. a. absorbed more energy from b. released more energy to c. was better insulated from 2. a. equal to b. greater than c. less than

Answer 1: A. It’s possible that the steel plaque had a higher temperature than the wooden block because it absorbed more energy from its surroundings.

Answer 2: C. If the steel and the wood received the same amount of energy from the Sun, then the specific heat capacity of the steel must be less than the specific heat capacity of the wood.

Explanation:

Specific heat capacity: It is the heat required to raise the temperature of one kilogram of the substance by one degree Celsius.

As steel is an alloy of metals and metals are good conductors of heat where as wood is not a metal and bad conductor of heat.

= change in temperature

if equal amount of energy is absorbed it means

masses are equal as given in question

Using above expression, as temperature of steel is more , so to get the same heat absorbed for both substances the specific heat capacity of steel should be less than specific heat capacity of wood.

c. is the answer
