Question

hese two states (liquid vs. gas)? (Lesson 3)
An ice cube tray full of water is put into a freezer. The water loses thermal energy and maintains 0ºC to undergo a phase change from a liquid to a solid. What energy change occurs in the particles in the water as it undergoes a phase change? (Lesson 3)
An increase in thermal energy leads to _____ (Lesson 4)
A student wants to collect data during an experiment about the transfer of kinetic energy in a sample of water and ice. What tool(s) will help her collect the necessary data? (Lesson 4)
A student records the temperature of several water samples as shown in the table below. Other than the temperature, the water samples are the same. Which sample has the lowest kinetic energy? (Lesson 5)

Answer 1

The energy change that occurs in the particles in water as it undergoes a phase change from a liquid to a solid is the absorption of energy.

An increase in thermal energy leads to an increase in the kinetic energy of particles.

To collect data during an experiment about the transfer of kinetic energy in a sample of water and ice, the student can use a thermometer to measure temperature and a scale to measure mass.

The water sample with the lowest temperature has the lowest kinetic energy.
