Yes energy can be measured directly with a calorimeter. The calorimeter will measure the temperature as it changes in a reaction.

What is principle of working of bomb calorimeter?
A bomb calorimeter is a type of constant-volume calorimeter used in measuring the heat of combustion of a particular reaction. Bomb calorimeters have to withstand the large pressure within the calorimeter as the reaction is being measured. Electrical energy is used to ignite the fuel; as the fuel is burning, it will heat up the surrounding air, which expands and escapes through a tube that leads the air out of the calorimeter. When the air is escaping through the copper tube it will also heat up the water outside the tube. The temperature of the water allows for calculating calorie content of the fuel
The combustion of titanium with oxygen produces titanium dioxide.?
When 1.310 g of titanium is combusted in a bomb calorimeter, the temperature of the calorimeter increases from 25.00°C to 68.10°C. In a separate experiment, the heat capacity of the calorimeter is measured to be 9.84 kJ/K. The heat of reaction for the combustion of a mole of in this calorimeter is __________ kJ/mol. 5.97-0.154-3119.43-1.55 × 104
What explains why a sealed calorimeter is a closed system?
thermal energy is not transferred to the environment.
What quantity is measured by calorimeter?
Final Temperature Initial Temperature Specific Heat Capacity of Calorimeter Plug the values into the equation: q = C( Tf - Ti ) , where C = specific heat, Tf = Final Temperature, and Ti = Initial Temperature.
Why calorimeter is kept in wooden box?
Because whilw measuring heat the energy can not be escaped
How is gravitational potential energy measured?
It is calculated, not directly measured.
What measures heat?
Heat is measured by a calorimeter. The calorimeter has been used to measure heat since 1782. Temperature on the other hand is measured by a thermometer.
What is considered when measuring kinetic energy?
Kinetic energy cannot be measured directly, but the kinetic energy is just 1/2 times the mass times the velocity squared, and velocity can be measured directly.
What piece of lab equipment is used to measure work?
There are different methods of measuring work. Work is defined as a change in state of energy from one form to another. Mechanical energy can be measured in horsepower, foot-pounds or their metric equivalent. This is measured with a dynamometer. Electrical energy is measured in watts, this is measured with a watt-ohm meter, or a volt-ammeter. Heat energy is measured with a thermometer, and potential energy can be measured with a calorimeter. For other types of energy there are different tools used to measure it. In order to determine work performed, the energy before the work is done must be measured, then the energy after the work is done is measured, then the work done can be calculated from the results.
How is heat measured in a calorimeter?
An insulated container with a thermometer to measure change of heat can be used as a calorimeter. Example a polystyrene cup with a lid.
What instrument measures heat energy?
UV vis spec, IR spec, FTIR, Raman, NMR, Mass spec, if it can be isolated you can go down the route of GC and LC (maybe even CE, but these are linked to detectors that may include the former. It depends really what you are looking for and on what timescale (i.e. stable or transient species)
What instrument measured heat?
A calorimeter measures heat. In contrast, a thermometer measures temperature.A thermometer bolometer - an instrument that measures heat radiation; extremely sensitive calorimeter - a measuring instrument that determines quantities of heatHeat is measured with a ThermometerThermometerThermometer or calorimeterThermometerthermometerHeat is measured with a thermometer.
What is the measuring device for thermal energy?
You can measure thermal energy by using a thermal couple. <ZeldaTutor> or u can use a calorimeter <ZeldaTutor>
What is using a calorimeter?
Heat is measured using calorimeter.A calorimeter is an object used for calorimetry, or the process of measuring the heat of chemical reactions or physical changes as well as heat capacity.
Unit for measuring heat?
The SI unit of heat is the Joule. It can also be measured in a calorimeter, where one calorie is the amount of energy needed to raise one gram of water by one degree Celsius.
