Question

How much heat (in Joules) is required to raise the temperature of 164 grams of water from 19. 2degree to 48. 9degree C? OUESTION 7 We have 110 grams of ice at -16. 9degreeC. Approximately how much heat (in Joules) do we need if we want to convert it into 110 grams of water at 18. 6degreeC? OUESTION 8 In part B of today's experiment, we place a 200g piece of metal with the initial temperature of 100degreeC in 200g of water. The initial temperature of water is 25degreeC after the metal and water reach thermal equilibrium, the temperature of the water is 38. 3 degreeC. What is the approximate specific heat of the metal? 230 J/kg degreeC 386 J/kg degreeC 900 J/kg degreeC 130 J/kg degreeC OUESTION 9 In the previous problem what do you suspect the metal to be? Silver Copper Aluminium Leod OUESTION 10 This is the last physics 1 lab of the semester. True False

Explanation / Answer

Q6.

Q(heat energy) = m*c* delta T where c is the specific heat capacity of ur material, in this case, water.

c(water) = 4.18J/ g* K
So Q = 164000g * 4.18 J/g*K *29.7K

= 2.036 * 10^7J
