What is the mass of water if it absorbs2625 J of energy and the temperature changes from 25.0*C to 36.4*C?
A 25.264 g cube of aluminum is cooled to a temperature of -15.26*C. If it's placed in 250.00g of water at 35.00*C, what would the final temperature of the aluminum and water be when the system comes to equilibrium? Assume that no heat is lost.
100g of water (specific heat=4.184 J/g*C) and 100g of a metal sample (specific heat=0.397 J/g*C) are heated from 25 degrees celcius to 75 degrees celcius. Which substance required more thermal energy to reach 75 degrees celcius?
