Question

a student puts a beaker of boiling water where it touches a block of ice. which two statements are true? a. thermal energy will move from the ice to the air. b. thermal energy will move from the air to the boiling water. c. thermal energy will move from the air to the ice. d. thermal energy will move from the boiling water to the ice.

Explanation:

1. Thermal energy transfer occurs from higher - temperature objects to lower - temperature objects. Boiling water has a high temperature (100°C at standard pressure), ice has a low temperature (0°C or below), and air temperature is likely between them or lower than boiling water.
2. For option A: Ice is at a low temperature, so thermal energy should not move from ice to air (air is likely warmer than ice, but even if not, boiling water is hotter than ice). So A is false.
3. For option B: Boiling water is at 100°C, which is higher than the temperature of air (usually around room temperature, much less than 100°C). So thermal energy should move from boiling water to air, not the other way. So B is false.
4. For option C: Ice is at a low temperature (0°C or below), and air is at a higher temperature (room temperature is typically above 0°C). So thermal energy will move from air (higher temperature) to ice (lower temperature). So C is true.
5. For option D: Boiling water is at 100°C, ice is at 0°C or below. So thermal energy will move from the higher - temperature boiling water to the lower - temperature ice. So D is true.

Answer:

C. Thermal energy will move from the air to the ice, D. Thermal energy will move from the boiling water to the ice
