Question

5) Which of the following are correct statements?

-Solid, liquid and gas co-exist at the triple point.

-A container is filled with a mixture of helium and oxygen gases. A thermometer in the container indicates that the temperature is 22C. Both molecules have the the same average kinetic energy.

-A bimetallic strip shown below, consists of metal G on the bottom and metal H on the top, and is active part of a circuit breaker. The coefficient of linear thermal expansion for metal G is greater than that of metal H. If the strip is electrical heated by excessive current, it will bend downward.

-Consider the spacer shown with a hole through its center. When the plate's temperature is increased, the hole will get larger.

-According to the ideal gas Law, PV = constant for a given temperature. As a result, an increase in volume corresponds to a decrease in pressure. This happens because the molecules are moving more slowly on average.

Explanation / Answer

1. True

All the three phase exists simultaneously at triple point.

2. True

for same temperature we have same kinetic energy.

3. True

It will bend downwards.

4. True

Hole will expand

5. false

Pressure is related to the molecules striking the walls, pressure is reduced as they strike the wall less.
