Quantifying Climate Change. Climate . change will increase temperatures in most places around the world in the coming decades. Temperatures in urban areas will go even higher due to the “heat island effect”. In order to measure the effect of climate change on worker productivity a heat stress index that incorporates temperature, humidity, wind speed and solar radiation is needed. . Introduction to Heat. Heat is a form of energy.. A large amount of energy ends up as heat.. Example: in a car some of the chemical energy stored in petrol is turned into heat energy. . Heat can have a significant effect on solids, liquids and gases (such as expansion).. Handling Heat & Cold.

How do we measure Temperature?. Thermal expansion . – The fluid in a thermometer’s bulb heats up and expands, increasing the volume until it flows up the tube of the thermometer.. Color change. – Some materials change color based on their temperature. Examples are forehead thermometers and mood rings.. Discovery Education Video:.
