Between D and E, the substance is ​ (a)   . This means heat energy is continually added and the temperature of the water ​ (b)   . Particles in the water move at about the same speed throughout the process, but some particles change from a ​ (c)   to a ​ (d)   .

• Melting

• Freezing

• boiling

• remains the same

• increases

• decreases

• liquid

• gas

Answer explanation

Between D and E, the substance is boiling, meaning heat energy is continually added and the temperature of the water remains the same. Particles change from a liquid to a gas during this process.

Why does an ice cube melt when dropped into hot liquid?

• The liquid absorbs energy from the ice.

• Energy from the liquid transfers to the ice.

• Energy from the ice transfers to the liquid.

• Cold from the ice transfers into the liquid.

Answer explanation

When an ice cube is dropped into hot liquid, energy from the liquid transfers to the ice, causing the ice to absorb this energy and melt. This process occurs because heat naturally flows from warmer to cooler substances.

Copper, Carbon Steel, and Zinc were all heated to 80^oC . Based on the chart, which material would have the most thermal energy?

• Copper

• Carbon Steel

• Zinc

Answer explanation

Carbon Steel has a higher specific heat capacity than Copper and Zinc, meaning it can store more thermal energy at the same temperature. Therefore, at 80°C, Carbon Steel would have the most thermal energy.
