BMAT- Physics Final Exam Questions and Answers

What do particles gain when heated Kinetic energy What does kinetic energy make particles do Move faster in gases and liquids /vibrate more in solids What is the unit of heat energy Joule What is temperature a measure of The average kinetic energy of the particles in a substance How to make the rate of cooling faster The greater the difference in temperature between objects How to make energy flow between places If there's a difference in temperature between the two places What holds particles close together in a solid Strong forces of attraction between particles Why are solids dense Particles are close together so they don't take up much space How are strong are forces of attraction between liquids Weaker then solids How does the amount of energy compare in solids compared to liquids More energy How does the amount of energy in gases compare to liquids and solids Even more energy How does boiling occur Big bubbles of gas form when particles have enough energy to overcome their attraction to eachother What are melting and boiling points affected by Impurities When melting or boiling, what is the energy used for Breaking intermolecular bonds When substances are condensing or freezing what happens to energy and temp It's released and temp doesnot go down till all the substance is liquid/solid What happens to most substances when heated Expand and volume increases
