A friend said the temperature inside a particular oven is 500 and the temperature inside a particular star is 50,000. You’re unsure whether your friend meant Celsius degrees or kelvins. How much difference does it make in each case?

You have to samples of equal mass one of gold and one of copper that you heat up to 120ﾟC. Gold has a specific heat of 126 j/kgK and copper has a specific heat of 387 j/kgK. Which sample reaches the temperature first? why?

You heat up a piece of hot metal with an emissivity of 0.1 until it glows. If the temperature of the metal is 3000 K, and the surface area of the metal is 0.1 meters squared, how much heat energy per second is transferred by radiation from the metal? 0.000001701 Joules per second (or Watts) 30 Joules per second (or Watts) 459270 Joules per second (or Watts) 45927 Joules per second (or Watts) 810000000000 Joules per second (or Watts)

A 2-kilogram [kg] projectile traveling at 100 meters per second [m/s] is stopped by being shot into an insulated tank containing 100 kilograms [kg] of water. If the kinetic energy of the projectile is completely converted into thermal energy with no energy lost, how much will the water increase in temperature in units of degrees Celsius [°c]?
