Why is it important to observe temperature change when two chemical are mixed?

The temperature change is needed to calculate the enthalpy change.

How do you calculate enthalpy change by bomb calorimeter?

You determine the change in the temperature of the bomb, and knowing the mass of substance, the calorimeter constant, and the change in temperature, you can calculate ∆H. Recall that q = mC∆T

Does Nitrogen PSI change with temperature?

Yes it changes with the chnage of temperature and you have to calculate the temperature correction factor

Is there any change in resistance of carbon composition resistor due to change in temperature?

yes, calculate it from temperature coefficient of resistance.

What is the delta triangle?

Delta means "change in"For example: Delta T means "change in temperature". To calculate this it would be (final temperature) - (initial temperature)

What is the equation used to calculate the change in heat energy?

Q=mC change in temperature

How do you calculate the change in temperature over time?

You can plot a graph to show the change in temperature over time, or deduct the final temperature from the original temperature to show the difference in temperatures.

How do you figure out the change in temperature if there is no change happening?

If there is no change occurring, and there are no data relating to past trends, there is no change to calculate - it is a constant.

How do you calculate the temperature change without knowing the initial or finish temp?

You cant.

How do you calculate gas volume with change in temperature?

the volume is directly proportional to the temperature so (as the temperature increases the volume increases ) so you can not calculate it except if you have a closed container and in that case the volume will equal to the capacity of the container I hope that you understand my answer

Is volume used to calculate change in thermal energy?

Yes, volume is usually used to calculate the change in thermal energy. Other than temperature, mass may also be used.

Assuming no change in temperature and pressure calculate the volume of O2 in liters required for the complete combustion of 14.9 L of butane C4H10?

Assuming no change in temperature and pressure, calculate the volume of O2 (in liters) required for the complete combustion of 14.9 L of butane (C4H10):

How do you calculate the heat absorbed released during a change in temperature?

This depends on specific heat of each material.

How can you Calculate the change in length of a steel bridge girder that will be exposed to a temperature change?

If L is the length of the girder, c the coefficient of thermal expansion and t the increase in temperature thenexpansion = L*c*t

What is the correct formula for calculating the change of temperature from Fahrenheit to Celsius?

To calculate Fahrenheit to Celsius, you take the temperature in Fahrenheit and multiply it by 0.8. Using the answer of that number, subtract 32 from it. That is your temperature in Celsius. To change that temperature back to Fahrenheit, you would add 32 to your Celsius temperature. After getting that answer, you divide it by 0.8 and Voislá, you're back at your temperature in Fahrenheit.

Why is a change in temperature a chemical change?

Temperature change is not a chemical change.

Why they calculate the airplane gasoline by kilos?

because a kilo doesn't change no matter the temperature or pressure. Mass is always the same.

What is used to calculate change in thermal energy?

E = kT, where E = energy ,T = temperature and k = Boltzmann Constant

What is the formula for change in temperature?

Change in temperature = New temperature minus Old temperature.

How do you calculate heat of neutralization?

Heat of neutralization is equal to mass of substance multiplied by change in temperature multiplied by specific heat capacity.

How do object change temperature?

how do objects change temperature

Calculate molar heat of sublimation?

You could calculate the molar heat of sublimation as long as you know by placing a known amount of a known quantity in a calorimeter and measuring the change in temperature during sublimation. Then use the equation E=mc(change in T) where E is energy in joules, m is mass, c is heat capacity, and T is temperature.

How is specific heat capacity used to calculate the energy change when a substance is heated?

Q=mCpdT. Q is the energy change, m is the mass of the object, Cp is the heat capacity of the object, and dT is the change in temperature.

Temperature can be used to recognize a phase change because during the phase change the temperature of the substance?

Temperature can be used to recognize a phase change because during the phase change the temperature of the substance does not change.

Does mass change with temperature changes?

Mass does not change with temperature
