Thermal Energy Ch. 1 (ET1) Quiz

A car mechanic had a bucket containing a substance in the gas phase. She left the bucket outside over the weekend. When she returned, the substance had changed phase, and the substance was in the liquid phase. How did this happen?

• Energy was transferred into the substance causing the phase change evaporation.
• Energy was transferred out of the substance causing the phase change freezing.
• Energy was transferred into the substance causing the phase change melting.
• Energy was transferred out of the substance causing the phase change condensation.

Cesar and Ming were investigating a see-through container of water. Water can be a solid, liquid, or gas. At first, Cesar and Ming said the water molecules were moving in place. Later , the water molecules were moving around each other. What caused the phase change?

• Energy was transferred out of the substance causing the phase change freezing.
• Energy was transferred into the substance causing the phase change evaporation.
• Energy was transferred into the substance causing the phase change melting.
• Energy was transferred out of the substance causing the phase change condensation.

Sarah measured the temperature of a pond near her house. Before she left for school, the water in the pond was 18°C. When she came home from school, the temperature of the pond was higher than it was in the morning. What happened to the water molecules while he was at school?

• The molecules got closer together.
• The molecules started moving faster.
• The water lost cold molecules.
• The molecules became larger.
