Document Summary
Measure of how hot or cold an object is. Molecules- particles something is made up of. Ex- kindergarteners running around= high temperature because particles are everywhere. When they are tired, low temperature ice= 0 degrees c, is same as 32 degrees f. Steam- 212 degrees f, same s 100 degrees c. Celcius is a bigger unit than fahrenheit, takes 180 f to be 100 c. Bigger change in temperature, bigger the expansion. Change of l = change of t. Change in l= linear expansion of l * change of t. Between 0 c and 4c, water shrinks from 0 to 4, and expands after. When you add heat to a substance, its temperature rises. Bigger mass, bigger quantity of heat needed to raise temperature by fixed amount. Scientist measure mass, change of temp, quantity of heat, measure data and figure out value of the constant and nature of the relationship amongst physical quantities.
