can someone please help me solve this lab?
calorie since it takes 1.00 cal to rai at units for the amount of heat may be The specific heat of water is used to define the value of a calorie since it takes 1 the temperature of 1 gram of water 1°C. The measurement units for the amount converted using the conversion factor: 1 calorie = 4.184 Joules. The specific heats of several substances are shown in Table 1. Notice that...

1) For part A, calculate q (the heat lost in calories) for copper and lead. The specific heats of these metals are in the background section. Then calculate q (the heat gained in calories) for the water in each case. Remember that you used 25.0 g of water in the experiment. Show your calculations 2)The heat lost by the metal and the heat gained by the water should be the same. Are they? If not, list possible sources of error....
