How Much Heat Is Required to Raise the Temperature of a Substance? In order to calculate how much heat is needed to raise the temperature of a given amount of a substance by a given number of degrees you can use the following equation: q=nCΔT Here, q is the heat, n is the number...
A more useful quantity in chemistry, physics and engineering isspecific heat capacity C, measured in units of heat per unit mass. Specific heat capacity units are usually joules per gram-kelvin, or J/g⋅K, even though the kilogram (kg) is the SI unit of mass. One reason specific heat ...
Subtract Tf from the temperature of the hot water just before you added it to the calorimeter. This will give you the change in the temperature of the hot water, Th. Multiply Th by 4.184 and the mass of the hot water to find out how much energy the hot water lost in joules. Step 1...
To calculate the amount of heat released in a chemical reaction, use the equation **_Q = mc ΔT_**, where **_Q_** is the heat energy transferred (in joules), **_m_** is the mass of the liquid being heated (in kilograms), **_c_** is the specific heat capacity of the liqu...
It was given in the problem that the mass of the sample is 2 kilograms, the amount of heat energy added to the sample is 1000 joules, and the temperature increase is 5 degrees centigrade. Step 2:Use the formula to calculate the specific heat of the substance. ...
How to Calculate Entropy In anisothermal process, the change in entropy (delta-S) is the change in heat (Q) divided by theabsolute temperature(T): delta-S=Q/T In any reversible thermodynamic process, it can be represented in calculus as the integral from a process's initial state to its...
How Does AC Work in a Car? A car's air conditioning works by manipulating pressure and temperature to move refrigerant between a liquid and gaseous state. The refrigerant enters the evaporator as a liquid, and the heat of the car transforms it into a gas. In its gaseous state, refrigerant...
How many joules of energy are required to raise the temperature of 50 grams of water from -100 degree C to 120 degree C? Calculate the energy needed to bring a cup of water (about 250 g) from 10 C to the boiling point. Then...
