Question

What does a decrease in temperature indicate about the molecules in a sample of liquid water? (3 points) a Decreased chemical energy of the molecules b Decreased kinetic energy of the molecules c Increased chemical energy of the molecules d Increased kinetic energy of the molecules

Answer 1

B. Decreased kinetic energy of the molecules

Step-by-step explanation:

The average kinetic energy of molecules determines the temperature of a substance.

Hotter objects

have faster-moving particles and higher temperatures

Temperature measures the averages because moving particles can absorb/release heat with each collision as heat is converted to kinetic energy and back.

Answer 2

option b is correct

Step-by-step explanation:

when the temperature of liquid solid and gases increases the kinetic energy of their molecules increases but when the temperature of liquid solid or gases decreases then kinetic energy of the molecule decreases
