### How many joules of energy are needed to heat 25.0 grams of steam from 100.0 degrees Celsius to 29.25 degrees Celsius?

Use this formula.
q(in Joules) = Mass * specific heat * change in temperature
I will use specific heat of water at 25 C. You can look up
specific heat of steam. You say " heat to " so I assume you have
final and initial heat backwards.
q = 25.0 grams H2O * 4.180 J/gC * (100.0 C - 29.25 C )
q = 7393 Joules

### How many joules of energy are necessary to heat sample of water with a mass of 46.0 grams from 0.0 to 100 C?

Assuming the water is liquid, the specific heat is about 4.186
joule/gram·°C, so to heat 46 grams of water would take about
192.556 joules/°C.
The specific heat of ice is about 2.100 Joules/g·°C so heating
46 g of frozen water would take about 96.6 joules/°C.
The specific heat of steam is about 2.020 Joules/g·°C so heating
46 g of water vapor would take about 92.2 joules/°C.

### What amount of heat energy is required to raise the temperature of 45 pounds of lead from 62 degrees to 100 degreesF?

Specific heat of lead = 0.160 J/gC
45 pounds (454 grams/ 1 pound)
= 20430 grams
Use.
q(Joules) = mass * specific heat * change in temp.
q = (20430 grams)(0.160 J/gC)(100 C - 62 C)
= 1.2 X 10^5 Joules
