The specific heat of liquid bromine is 0.226 J/(g•°C). How much heat (J) is required to raise the temperature of 31.2 g of bromine from 25.00°C to 27.30°C?
A sample of aluminum metal absorbs 9.86 J of heat, upon which the temperature of the sample increases from 23.2°C to 30.5°C. Since the specific heat capacity of aluminum is 0.90 J/(g•°C), the mass of the sample is:
Which one of the following is an exothermic process?
condensation of water vapor
What is the specific heat of a substance if 373 J is required to raise the temperature of a 312 g sample by 15°C?
The internal energy of a system is always increased by:
adding heat to the system
withdrawing heat from the system
a volume compression
having the system do work on the surroundings
4 Al (s) + 3 O2 (g) → 2 Al2O3 (s) ΔH° = -3351 kJcauses the temperature of its surroundings to increase. This reaction is __________, and therefore heat is __________ by the reaction.
Knowing that its specific heat capacity is 4.18 J/(g•°C), how much would the temperature of 16.0 g of pure water increase by when 670. Joules of heat are applied?
Which one of the following is NOT a change in state of matter (or phase)?
The specific heat capacity of lead is 0.13 J/(g•°C). How much heat (in J) is required to raise the temperature of 15 g of lead from 22°C to 37°C?
5.8 x 10-4 J
