How much heat would be required to raise 499 g of water from 111 oC to 251 oC? (You need to know what physical state water is in for the temperature range we're looking at.) Specific heats of water in different physical states H2O (s) = 0.497 cal/g. oC H2O (l) = 1.00 cal/g. oC H2O (g) = 0.490 cal/g. oC

An electric heater supplies 11.6 joules of energy to 12.1-g sample of CH3CO2H originally at 22.7 °C. Compute the final temperature (in °C). °C the tolerance is +/-2%

While heating two different samples of water at sea level, one boils at 102°C and one boils at 99.2°C. Calculate the percent error for each sample from the theoretical 100.0°C.

At a festival, spherical balloons with a radius of 220. com are to be inflated with hot air and released. The air at the festival will have a temperature of 25 cand must be heated to 100 c to make the balloons float. 2kg of butane fuel are available to be burned to heat the air. Calculate the maximum number of balloons that can be inflated with hot air..
