Question

ethan made a diagram to compare examples of the first and second laws of thermodynamics. what belongs in the areas marked x and y? x: the internal energy of a piston system increases as heat is added and rises to a cool area y: as thermal energy is added to a container, some of the energy is lost to the environment x: as thermal energy is added to a container, some of the energy is lost to the environment y: the internal energy of a piston system increases as heat is added and rises to a cool area x: a cold spoon placed in hot liquid gets warmer y: thermal energy is converted to light energy x: thermal energy is converted to light energy y: a cold spoon placed in hot liquid gets warmer

Explanation:

Step1: Recall first - law of thermodynamics

The first law of thermodynamics is about conservation of energy in a system. Heat added to a system can change its internal energy. A cold spoon placed in hot liquid getting warmer is an example of heat transfer which is related to the first - law as energy is transferred from the hot liquid to the cold spoon.

Step2: Recall second - law of thermodynamics

The second law of thermodynamics is about the direction of energy transfer and entropy. The conversion of thermal energy to light energy (for example, in an incandescent bulb where heat is used to produce light) is related to the second - law as it involves an irreversible process and energy transformation with some energy loss in the form of entropy.

Answer:

C. X: A cold spoon placed in hot liquid gets warmer; Y: Thermal energy is converted to light energy
