SCIENCE HEAT ((energy required to raise temp. to 1'c:check: mercury=0.1J, 200ml of water out of tap is 21'c --->31'c (formula= 200 x 4.2 x 10'c= 2100joules) , specific heat capacity= wanting to raise temp. by specific temp.), body TEMP. is 37'c, kinetic energy= movement, drill (KINETIC ENERGY---->HEAT ENERGY), heat measured in joules, HEAT IS THE MOVEMENT OF PARTICLES, heat flows from hot to cold-until both object are at the same temperature, temp. is a measure of how hot or cold something is, temp. measures energy, nature is about balance., The rapidly moving particles in the hot object transfer some of their energy to the particles in the colder object until they are the same temp., the larger the temp. difference the faster the transfer., cool objects in warm places take in energy from their surroundings., 4.2 joules to raise the temp. by 1'c a substance of 1 gram, heat(J) = mass (g) x specific heat capacity x change in temp.
