Convert: 150°C to °F; 25°F to °C, -50°F to °K, 100°C to K, 400K to 'c etc. How much heat is required to increase the temperature of 40g water from 25°C to 100°C? Specific heat of water is 1 cal/g°C. How much heat is required to convert 50g ice at 0°C to water at O'C? Latent heat of fusion for ice LF80 cal/g. How much heat is required to increase the temperature of 20g iron from 25°C to 300°C? Specific...

The answer is 13626 J. However, I kept getting an answer around
the 14,000 range. Please show all of your work in this problem and
how you will reach the final answer of 13626 J.
Calculate the heat required in Joules to convert 18.0 grams of water ice at a temperature of -20° C to liquid water at the normal boiling point of water. Given: -specific heat of ice = 2.09 J/g°C -specific heat of liquid water = 4.184 J/g°C...

i got this question wrong. the book previously said that the
units of entropy are J/(mol*K). you can get mol with the grams that
they gave, so why not use it?
Example: If, in a reversible process, 6.66 x 10 J of heat is used to change a 200 g block of ice to water at a temperature of 273 K, what is the change in the entropy of the system? (Note: The heat of fusion of ice = 333...
