Question

A coffee-cup calorimeter of the type shown in Figure 5.18 
contains 150.0 g of water at 25.2 °C. A 200-g block of silver 
metal is heated to 100.5 °C by putting it in a beaker of boiling 
water. The specific heat of Ag(s) is 0.233J>1g # K2. The Ag is 
added to the calorimeter, and after some time the contents 
of the cup reach a constant temperature of 30.2 °C. 
(b) Determine the amount of heat gained by the water. The 
specific heat of water is 4.184 J>1g # K2.

Accepted Answer

everyone's here. We have one grand block of copper metal That's heated to 95°C. It was dropped in a coffee cup Kalorama containing g of water At 24.5°C. And the temperature inside the cup changed to 34.9°C after one hour. Never asked what is the heat released by the proper block? We have a specific heat of copper. We went through 85 Joel's program. Sound degrees Celsius. Recall that the amount of heat transferred. It was the mass of the solution. The specific heat of the solution times the temperature change. So cute is what we're looking for. The mask is one g. This is a big key capacity of copper is 0. jobs. Our graham toms Greece Celsius and the temperature change Gonna be 34.9 three Celsius minus 95 degrees Celsius. We get negative 60.1 Celsius plug in the values to find the heat released by the copper block. Gonna get cute because one graham I'm 0.385 goals program, times degrees Celsius. I was gonna get a 60.1 three Celsius. Ever cute. Gonna get negative 23.1 jaws and negative means that the heat is lost. Thanks for watching my video and I hope it was helpful
