Temperature vs heat examples
WebTemperature is literally defined as what we measure on a thermometer. Heat is often confused with temperature. For example, we may say that the heat was unbearable, when … WebWe know that when matter is heated, it usually expands and hence its volume increases. When matter cools, it contracts (exception: water freezing). Since density equals mass divided by volume: If the volume is increased, and mass stays constant, density must decrease (i.e. density is inversely proportional to volume).
