A beaker of 98°C liquid was set on a table in a 72°C lab. A group of students monitored the temperature of the liquid for 45 minutes but had to leave class when the bell rang. When they return tomorrow, what will be the

• The temperature of the liquid will be 0°C because that is the lowest temperature it can reach.

• The temperature of the liquid will be 98°C because heat from the lab will start to warm it back up.

• The temperature of the liquid will be 72°C because once it reaches the temperature of the room, it will be at equilibrium.

• The temperature of the liquid will be 0°C because heat will continue to leave the beaker until it reaches freezing.

Joshua conducted an experiment. He placed granules in a beaker of water. He measured the temperature before and after. The change in temperature gives Joshua information about the mixture best described by which of the following

• The ability of the mixture to conduct an electric current

• The current arrangement of atoms in the mixture

• The decrease in the kinetic energy of the particles

• The quantity of heat released by the mixture
