In this problem, we need to calculate the amount of heat involved in four processes that are given, and we have to calculate the amount of heat either released or excerpt, being both used on calories. The first exercise is related to heating up a mask off 5.25 grams off water from 5.5 Sell shoes to 64.8 Celsius. Okay, again, this is a hit capacity problem under for the central formula that I'm going right here. He's amount of heat absorbed for release equals the mass of the substance times they hit the positive, the soft string, which is a constant that we finding that they will provide it times the different in the temperature or final temperature minus initial temperature. Okay, so this is the formula that we're gonna be referring through. The development of these exercise the amount of heat absorbed by water. In these process. He's in mice of water. My £0.25 times that he'd composite of war. E news, which is four point 184 yours. Program spur sells shoes times the difference in temperature just 68.8 sort of 64.8 by a temperature minus 5.5. Initial temperature on the on the delta is 59.3 Celsius, so it's just cancel grounds. Council on the answering Your species 1300 three 1000 300 on three use in calorie. The answer is even when you think the U they hit capacity constant the calories for water. This is one calorie her grounds. Purcell Shoes times does that the which is the same 59 points today. So is this Council Cramps Council, and in this case, the answer is 300 it's 111. God is you got in B exercise. We have to calculate the amount of water that is lost. The amount of heat that is lost when 75 grams of water goes down from 86.4. Sell shoes toe to point one sell, it says we do the same thing. Must off water times that hit capacitor border in mules. First times the difference in temperature, which is 2.1 final temperature minus 86.4 initial temperature. And the answer is that Delta bi East negative 84.3 salt is OK, so it's just gone solo Crimes Counselor for the answer. These negative 26,000 453 fuels cool to obtain the answer in calories. We do the same thing, but we use. They hit capacity constant in colonies for grants for sales is times that that the which is the same. We cancel their associates on the grounds we get. They got these 6000 323 galleries. Okay, Next we deal with hearing 10 grams of silver from 112 cells. Use to 275 Celsius. Good to solve these these case, we need to find the hit capacity of cylinder. The news Ah, first and then the calorie. So we multiply that 10 grams The mass times The hit capacity of silver in use, which is poin 235 fuels programs. Our cells use times the difference in temperature, which is to 75 final minus 1 12 You need chunk now that he's won 63 sell shoes. So it's just cancel crimes. Consul's and the answer ease. 383 fuels. Sorry. Yeah, 383 mules. To get these heat in calories, we used the heat capacity of silver in calories, which is 0.0 562 Carla is four grams per Celsius times the same built a T. So she's gone. So Grand council. And the answer is 91.6 galleries. Okay, Andi. Finally, we need to calculate the amount of heat that is lost when 18 grams of gold cools down. So it's amount of heat release by 18 grams of gold when gold cools down from 224 Celsius to 118. So let's use okay To calculate the amount of heat release by this massive gold, we need to find the hit capacity of gold first Mules, which is 0.1 to 9 fuels for grounds. Purcell issues times different in temperature. 1 18 minus 2 to 4 on delta is negative. 106 We can serve. The soldiers would cancel the grounds on the concept being used bees. Sorry, the answer in mules. He's negative. 246 yours to obtain this heat. This amount of heat release being calories. We use the incapacity off gold in calories, which is 0.3 08 Galleries, her grounds. Purcell Shoes times, Delta T. Which is the same They give 106 So it's just concert grounds. Council on the answer is negative. 58.77 Gallaghers. Okay, so these two are. The answer is related to the amount off heat released by gold this toe are the answers related to the amount toe heat absorbed by silver. These two answers are related to the amount of heat release by water, and these two are the answers related to the amount of heat out sort my war.
