HVAC Exam 1 1. Matter exists in what three forms?: solid, liquid, gas 2. What is temperature measured by? Quantity or intensity: Intensity 3. Define British thermal unit (Btu): Measure of heat energy - amount of energy needed to raise 1 lb of water 1 degree F 4. How much heat is required to raise the temp of 100 lb or water from 70F to 120F: Q=1000lb*(1btu / change of temp) so 1000*(1/ 50) = 50,000
