Temperature and Thermal Energy (assignment) Which of these would have the lowest kinetic energy?
-boiling water
-*ice water
-refrigerated water
-water at room temperature

Joshua is preparing a report to show the relationship between average kinetic energy and temperature. Is his graph accurate? Explain your answer.
-Yes, his graph is correct because it shows that as the average kinetic energy increases, so does the temperature. This is called a direct relationship

Jenny measures the temperature inside a cave to be 10°C. The temperature outside the cave is about 30°C warmer.
How does the kinetic energy of the air molecules inside the cave compare to the kinetic energy of the air molecules outside the cave?
The kinetic energy of the air molecules inside the cave is *less than* the kinetic energy of the air molecules outside the cave.

Which temperature scale has the highest value for the boiling point of water?
*kelvin*

At which temperature does the motion of atoms and molecules stop?
-0°C
-0 C
-0°K
-*0 K

Which scale is being described?
-Water freezes at 32 *degrees fahrenheit*
-Water freezes at 0 *degrees celsius*
-Water freezes at 273 *kelvins*

An outside thermometer reads 57°F. What is this temperature in °C? Round your answer to the nearest whole number.
-*14
-49
-71
-135

Christopher conducts an experiment in which he tests how much sugar dissolves at different temperatures of water. One step requires him to use water with a temperature of 32.5°C. What is this temperature in kelvins? Record your answer to the nearest tenth.
*305.5 K*

Explain what happens to the average kinetic energy, thermal energy, and temperature of a substance when the particles in the substance slow down.
-The particles in a substance slow down when the average kinetic energy of the particles decreases. As the average kinetic energy decreases, the internal energy decreases, and so the thermal energy decreases. As the thermal energy of the substance decreases, the temperature decreases.
