Do different liquids expand by different amounts for the same rise in temperature?
Yes, different liquids have different coefficients of volume expansion, which means they expand by different amounts for the same increase in temperature. This is because the molecular structure and composition of liquids vary, leading to different responses to changes in temperature.
What expands when it is heated?
When heated, most substances expand due to the increase in kinetic energy of their atoms or molecules. This leads to an increase in the average distance between the particles, causing the substance to expand.
Would brass or iron expand in a bimetallic strip?
Brass and iron have different coefficients of thermal expansion, so when exposed to a change in temperature, they would expand by different amounts. This difference in expansion causes the bimetallic strip to bend due to the unequal expansion of the two metals.
Do all gases expand equally when heated?
No, different gases have different coefficients of thermal expansion, which means they expand at different rates when heated. The expansion is determined by factors such as the molecular weight and the specific heat of the gas.
A bimetallic strip used in thermostats relies on the fact that different metals have different?
coefficients of thermal expansion. When the strip is subjected to temperature changes, the two metals expand by different amounts which causes the strip to bend. This bending is used to trigger mechanical switches in the thermostat to control the temperature.

When do substances expand?
Yes.
Do substances expand when hot?
Yes.
Do substances expand on heating?
yes
What do substances do when heated because of the molecules?
they expand
When most substances absorb heat energy they?
expand
Why substances often expand when they are heated?
because the particles
What expands when its heated?
Most substances expand when heated.
What expands when it is heated?

What are substances that expand and contract called?
Materials that expand and contract in response to changes in temperature are typically referred to as thermal expansion materials. These materials expand when heated and contract when cooled, which can be useful in various applications such as in thermostats, bimetallic strips, and expansion joints.
What do most substances like the liquid in a thermometer do when they are heated?
expand
Does aluminium swell?
No, although it does expand with heat as do most substances.
