Calorimetry a. How much heat needs to be taken from 0.5 kg of ethyl alcohol as a gas at its boiling point of 78.0 C to a solid at its freezing point -114 C if the latent heat of vaporization...
Rivets can be cooled before they are put in place, thus when they reach equilibrium temperature they are more firmly fixed in place. If the volume expansion of iron is 35.0 X 10-6...
If you want to find the latent heat of fusion, you take a cup with 0.755 kg of water at 30.00 C and drop 0.0850 kg of ice initially at 0.000 C and it all reaches an equilibrium temperature of...

Does metal conduct heat quickly true or false
This is one of the questions on my review guide my teacher gave me and I have a test tomorrow and have no idea how to find the answer to this question! If someone could give the formula to find mass...
There are 12 cans of pop in cooler, each can weighs .35kg, and the specific heat for pop is 3800. The temperature in the cooler is 5C. Someone places a water mellon in the cooler that has a...
I'm stuck on this one How many grams of methane must be combusted to heat 1.00 kg of water from 25.0 °C to 90 °C, assuming H2O(l) is the product of the reaction and no heat...
I'm not sure what I need to do here... If 25.0 g of ethanol at 5.0 °C is mixed with 50.0g of ethanol at 75.0 °C, what with the final temperature of ethanol be, assuming no...
A .2kg of blue metal at 100ºC is place into 1.5kg of water initially at 25ºC. If the final temp of the two is 53ºC, what is the heat capacity(specific heat) of the blue metal? ...
Find the final temperature go the H20(l) sample.
A thermal power plant produces 82 MWh/d of excess heat energy. How many homes could be heated from this source assuming heating requirements of 40 kWh/d per house?
58. Which has the higher specific heat capacity: an object that cools quickly or an object of the same mass that cools more slowly?
