when measuring the temperature of an object in heat, you are finding what?
what is the specific heat of water?
a higher concentration of btus due to different composition (heat content)
although two objects contain the same number of btus, what makes one hotter than the other?
total heat a substance contains
what does the quantity of heat depend on?
the heat required to change the temperature of 1 lb. of a substanc 1 degree F
what is specific heat?
how have all the specific heats been determined?
fractions, multiples, or decimals of the specific heat of water
how is the specific heat of a substance expressed?
what is the specific heat of copper?
how many btus are necessary to rais 10 lbs. of copper 10 degrees F?
heat that causes a change in temperature with no change in state
what is sensible heat?
what state is a substance in which molecules are packed tightly together?
what state is a substance in which molecules loosly together?
vapor or gasses
what state is a substance in which molecules have lost their bonds
total heat the object contains
what determines the state of a substances?
measuring temperature with a thermometer
how is sensible heat determined?
how many btu's must be removed from 10 lbs of water to lower its temperature from 50 degrees F to 40 degrees F?
heat added or removed from a substance to cause a change in state from a solid to a liquid or a liquid to a solid with no temperature change
what is latent heat of fusion?
heat added to a liquid causing a change of state to gas
what is the latent heat of vaporization?
how many btu's does it take to change 1 lb of 212 degree F steam into water at 212 degrees F?
how many btu's does it take to change 1 lb of 32 degree F ice into water at 32 degrees F?
heat removed from a vapor causing a change in state to a liquid with no change in temperature
what is the latent heat of condensation?
what change in temperature takes place as ice melts?
if the water temperature is 212 degrees F and additional heat is added, what happens to the water temperature?
turns to steam
what happens to water if its temperature is 212 degrees F and additional heat is added?
latent heat of vaporization
what is the heat that causes the water to boil called?
