Re: Q MCT Practice Problems
As you are looking for Q MCT Practice Problems material to do preparation of an entrance exam, so on your demand I am providing same: Example 1: How much heat (in calories) is needed to raise 20 grams of water from 5 oC to 40 oC? Q = mc(Tf—Ti) Q = x m = 20 grams c = 1 cal/goC (this is the specific heat of water) Tf = 40 oC Ti = 5 x = (20 g) (1 cal/goC)(40 -5 0C) = 700 cal Example 2: How much heat (in calories) is needed to raise 140 grams of water from 20 oC to 25 oC? Q = mc(Tf—Ti) Q = x m = 140 grams c = 1 cal/goC (this is the specific heat of water) Tf = 25 oC Ti = 20 oC x = (140 g) (1 cal/goC)(25-20 0) = 700 caL Example 3: How much heat (in calories) is needed to raise 250 grams of water from 80 oC to 87 oC? Q = mc(Tf—Ti) Q = x m = 250 grams c = 1 cal/goC (this is the specific heat of water) Tf = 87 oC Ti = 80 oC x = (250 g) (1 cal/goC)(87—80 0C) = 1750 cal Example 4: How many calories are needed to raise 50 grams of iron from 55 oC to 200 oC? The specific heat capacity of iron is 0.11 cal/goC. Q = mc(Tf—Ti) Q = x m = 50 grams c = 0.11 cal/goC Tf = 200 oC Ti = 55 oC x = (50 g) (0.11 cal/goC)(200– 55 0C) = 797.5 cal Q MCT Practice Problems material |
