## What happens to the density of a material when temperature increases?

When a substance is heated its volume increases and so the density decreases. In liquids and gases, as the temperature increases, volume increases and therefore density decreases considerably.

## Does material density change with temperature?

Density changes with temperature because volume changes with temperature. Density is mass divided by volume. As you heat something up, the volume usually increases because the faster moving molecules are further apart. Since volume is in the denominator, increasing the volume decreases the density.

What happens to the density of a material?

Density is the amount of mass located in a specific volume. The density of an object can change if either the mass or volume of the object is changed. Fluids, such as water, have a certain density. If an object is more dense than water, it will sink; if it is less dense than water, it will float.

What is effect of temperature on density?

Density of a substance decreases with increase in temperature because increases the volume.

### What happens to density when the temperature decreases?

When temperatures increase, objects expand and become larger and therefore the density decreases. When temperatures decrease, objects condense and become smaller so density increases.

### What happens to the temperature and density of the material between B and C?

Question Five: What happens to the temperature and density of the material between points B and C? As the fluid flows between these points, it adjusts to the lower temperature at the top of the mantle and cools down. This slows the particles, causing them to move closer together, increasing the density.

Does density decrease with temperature?

Density is directly proportional to pressure and indirectly proportional to temperature. As pressure increases, with temperature constant, density increases. Conversely when temperature increases, with pressure constant, density decreases.

When a material is heated does its density increase?

Since the mass stays the same, the ratio of mass to the volume decreases. In other words the density of the substance decreases as it is heated. Water is an exception: when water goes from the solid to liquid state, its density increases.

#### What happens to the temperature and density of the material between D and A?

Where is the density of the material greater, at point B or point C? What happens to the temperature and density of the material between points D and A? Heat from the core causes the temperature of the material to rise, this means the density will decrease since hotter material is less dense than cooler material. 8.

What happens to the temperature and density of the material between points D and A?

What relationship do you observe between the temperature and density?

The relation between density and temperature is inversely proportional. Change in density will be reflected in a change in temperature and vise-versa.
