Explain how to calculate heat gained by a calorimeter if the heat lost was -2654.3 J and the heat gained was 3030.5 J. What is the heat capacity of a conductive calorimeter ? Calculate the energy needed to heat a cube of copper with a volume of 13.0 cm3 from 15 degrees Celsius to 27...
To calculate the power or electricity cost of your air conditioner,multiply the electricity consumption or the per kilowatt hour (kWh) by the tariff rate(e.g. 20 cents/kWh). To get the energy consumption (kWh), simply multiply the appliance wattage (kW or W) by the number of hours you ...
How to calculate the approximate amount of heat necessary to raise the temperature of 50 grams of liquid water from 10.0 degrees C to 30.0 degrees C? Why is a measured amount of water needed to determine the specific heat of a metal object?
Example 1: Calculate the temperature change that results from adding 250 J of thermal energy to 0.50 moles of mercury. Visualize the diagram of the Heat System and Surroundings with the arrow direction going into the system. Use the formula: _q = nCmΔT_ Since you are asked for the change...

We know that the amount of solution and the amount of heat generated is directly proportional. If we have less of one solution, we expect less heat to be generated. Our final temperature would be lower than expected, and the amount of heat that we calculate would be lower than predicted....
Write down the line of best fit from your graph. Plug in 5 minutes for x and calculate y (the extrapolated temperature at 5 minutes). We'll call this extrapolated temperature Tf. Step 13 Subtract Tf from the temperature of the hot water just before you added it to the calorimeter. This...
How To Calculate Bullet Impact You can effectively calculate the impact of a bullet via the following series of steps. Step 1 Collect the required information for the ammunition under consideration. You will need to know the bullet weight, measured in grains, which is listed on the ammu...
How to Calculate IRMS. The current in an alternating current circuit varies continuously in direction and magnitude. Calculations involving the current don't therefore consider the current at any single instant. They instead use the root mean square curr
They gained the support of many. Ten years later, the International Whaling Commission finally banned commercial whaling. It then changed its focus to not only whales but to seals and sea turtles as well. Though they made great progress with these animals, they came to the conclusion that ...
