Difference between isothermal and isoperibol calorimeter?
An isothermal calorimeter is a tool used to bind small molecules to larger macromolecules, and determine the thermodynamic parameters of interactions in a solution. An isoperibol calorimeter measures the heat created by a sample burned under an oxygen atmosphere in a closed vessel surrounded by water, in controlled conditions. The measurement is known as a BTU value.
What are the chemical reactions that happen when a nuclear plant explodes?
That would depend on what is ignited. If you are referring to events such as the accident in Chemobyl. Upon meltdown, the nuclear core which is partly composed of graphite burned releasing radioactive smoke. There must be many chemical combustion reactions of all sorts happening depending on what has caught on fire. The major concern is the radioactive debris from the core spewing into the environment. There would not be a large explosion such as a nuclear bomb because the uranium used in the core is not enriched enough to detonate.
Can you get burned at 50 degrees C?
it will be a higher temperature then your body but would not think it will burn if you have it on you for a short time
Is an automobile engine cylinder can ignite gas fumes?
Some fuel, use gasoline is vaporized in the engine and is ignited (burned) in the cylinders. Usually a spark is provided electrically thru the tip of the spark plug to start the fuel burning. This burning is very rapid, like an enclosed explosion.
How would you use tepid in a sentence?
The temperature of the coffee was quite tepid, and he burned his tongue tasting it. Now stop posting your homework on here! Get a dictionary!
How are calories determined for packaged food?
Calories are determined by a device called a calorimeter. a calorie is the amount of energy (heat) released from a food. so that is exactly what a calorimeter does, measures the amount of heat food has given off. A piece of food is massed, ignitted and set inside the calorimeter. a tray of water sits above the ignited food. when the food is burned out, experts analyze the temperature of the water - thus how calories are determined.

How is petroleum energy released?
It is released by being burned, or ignited.
What does non flammability mean?
Non-flammable means that cannot be burned or ignited.
What does flammable mean in science?
Non-flammable means that cannot be burned or ignited.
What does non-flammable mean in science?
Non-flammable means that cannot be burned or ignited.
What type of calorimeter is junkers caloriemeter?
A Junkers Calorimeter is a device for determining the heating capacity of a gas - that is, how many joules one can get by burning a set volume of that gas. It's usually [natural] gas from the mains, but could be any flammable gas. The device is essentially a Bunsen burner with a cooling jacket. The jacket is cylindrical in shape, about 80cm tall, with water running through it. The burner sits inside the cylinder. The calorimeter allows the user to measure the temperature of water flowing in and flowing out. Once steady-state is reached, with those two temperatures steady, the water flowing through is collected for a specified period of time. Measuring the mass of the water and the temperature rise in the water, the operator can calculate the number of joules which went into the water to heat it. There is a flow meter on the fuel gas, so the operator can also calculate the volume of gas that was burned in the same time period. The amount of energy, in J, available per litre of gas can then be calculated. A Junkers calorimeter is a flow calorimeter, with heat transfer happening continuously, as opposed to a batch calorimeter. The design dates back to the late 1800s.
Is coal an energy?
Not really. Energy is released when coal is burned. It is not coal itself, but the reaction of oxygen and coal once ignited that results in energy.
Is graphite wood?
No, graphite is a mineral and is composed entirely of Carbon atoms. Wood is a living material which contains celulose, among other substances, when it is burned the remains do contain carbon but there are also other elements present.
What temperature does a fire quit burning?
we burned a tree doow3n and the temperature was -675C
When crystalline C6H12O6 is burned in oxygen carbon dioxide and water vapor are formed?
C6H12O6 + 6O2 -> 6CO2 + 6H2O Yes, a special form of a combustion reaction called respiration., or if ignited and actually burned water vapor will form.
Do fossil fuels increase the temperature?
Not until burned.
