answered-by-expert Expert Answer
When the temperatue increases the volume of matter increases and density decreases. It is because the mass of that object remains same. For example, if the temperature of iron bob is increases its volume increases and density decreases while the mass is same. This is because it undergoes thermal expansion. When the temperature decreases then the volume decreases and the density increases keeping mass constant this is called contraction of substance due to the loss of heat.
