## What happens to the volume when liquid is heated?

During experimentation, with regard to volume, liquids generally expand when heated and contract when cooled. In simpler terms, liquids increase in volume with substantial increase in temperature and decrease in volume with significant decrease in temperature.

When a liquid is heated what decreases?

And mass remains the same here but volume increases due to increase in temperature so, density of liquids decreases with increase in temperature that is on heating.

### When a liquid is heated which of the following quantity changes?

Volume: changes and increases with rise in temperature.

Does heating up a fluid increase or decrease its viscosity?

The liquid viscosity is highly affected by the heat. The viscosity decreases with an increase in temperature. Most liquids suffer the exponential relationship (Seeton, 2006) between temperature and viscosity rather than linear form (Fig. 6.1).

#### When a liquid or gas is heated its density increases or decreases?

i.e. with increase in temperature the mass of the liquid remains the same but the volume increases. So the density will decrease by increasing the temperature.

When a liquid is heated to raise its temperature?

When the temperature is increased, the volume increases. As mass is constant with respect to temperature, Volume and density are inversely proportional. SO when temperature increases, volume also increases and the density decreases.

## Does heat decrease volume?

The volume of air in the balloon will increase when exposed to hotter temperatures, and decrease when exposed to colder temperatures. If we look at the ideal gas law, we can see that temperature and volume have a direct relationship. As one goes down, so does the other, assuming all other factors remain constant.

When a liquid is heated its density increases or decreases?
