Question

One way to get a very snug fit in manufacturing is to make a peg slightly larger than the hole it goes into. The pieces can be put together when they are at different temperatures. When they come to thermal equilibrium they will be almost impossible to get apart without breaking.

A metal peg needs to fit into a hole in a metal block. Which pieces should you heat or cool to more easily put them together?

heat the peg, cool the block

cool both the peg and the block

it doesn't matter as long as you do the same thing to both: either heat both or cool both

heat both the peg and the block

cool the peg, heat the block

it doesn't matter as long as you do different things to each: heat one and cool the other

2.) Consider a container filled with an ideal gas. In which cases would the change described cause the pressure of the gas to increase?

In each case the only change to the gas is the one described. All other properties are held fixed while that change is made.

Group of answer choices

add more particles

increase size of container

decrease temperature

remove particles

increase temperature

decrease size of container
