Across
  1. 2. energy an object has due to its motion
  2. 5. condition caused by the loss of too much body heat
  3. 7. when two surfaces interact and cause a conversion of mechanical energy (like kinetic energy from movement) into thermal energy
  4. 10. substances that thermal energy can easily move through
  5. 12. state in which all parts of a system are at the same temperature
  6. 13. the measurement of the number of particles present in a given volume, often in a mixture or solution
  7. 14. a type of thermal energy transfer in which currents carry thermal energy from one part of the fluid to another
  8. 15. transfer of thermal energy by direct contact of two objects or portions of matter
  9. 17. the SI base unit of thermodynamic temperature (equivalent in size to the degree Celsius), first introduced as the unit used in the Kelvin scale
  10. 18. gives the amount of useful thermal energy stored in unit volume of a substance
  11. 19. sum of the kinetic energies of all the particles that make up an object
Down
  1. 1. tendency of particles to spread out when the kinetic energy increases
  2. 3. a measure of the average kinetic energy of an object’s particles
  3. 4. a state in which opposing forces or influences are balanced
  4. 6. describes a fluid's resistance to flow
  5. 8. of or denoting a scale of temperature on which water freezes at 0° and boils at 100° under standard conditions.
  6. 9. of or denoting a scale of temperature on which water freezes at 32° and boils at 212° under standard conditions.
  7. 10. substances that thermal energy cannot move through or thermal energy moves slowly though
  8. 11. the movement of particles from an area of high concentration to an area of low concentration until equilibrium is reached
  9. 16. the process of thermal energy transfer by electromagnetic waves
