An exothermic reaction is carried out in an closed system and an isolated system. Which of the following is true? There will be no temperature change in the isolated system, since heat can not move into or out of the system. The temperature change in the isolated system will be greater than the temperature change in the closed system. The temperature change in the closed system will be the same as the temperature change in the isolated system. The temperature change in the closed system will be greater than the temperature change in the isolated system.

An exothermic reaction is carried out in an closed system and an isolated system.
Which of the following is true?
There will be no temperature change in the isolated system, since heat can not
move into or out of the system.
The temperature change in the isolated system will be greater than the
temperature change in the closed system.
The temperature change in the closed system will be the same as the
temperature change in the isolated system.
The temperature change in the closed system will be greater than the
temperature change in the isolated system.

To conduct an experiment, a scientist places a small piece of aluminum in a test tube
and adds sodium hydroxide solution. Bubbles of gas are produced and the outside of
the test tube becomes hot to the touch. Which of the following is true?
The reaction is endothermic, and the system gains energy from the surroundings.
The reaction is exothermic, and the system loses energy to the surroundings.
The reaction is endothermic, and the system loses energy to the surroundings.
The reaction is exothermic, and the system gains energy from the surroundings.
