**What is the formula to calculate calories?**

It needs your age, weight, and height. There are two separate formulas for men and women: **For women â€“ BMR = 655.1 + (9.563 * weight in kg) + (1.850 * height in cm) – (4.676 * age)** . For men â€“ BMR = 66.5 + (13.75 * weight in kg) + (5.003 * height in cm) – (6.75 * age) .

**Why do we use q mc âˆ† t?**

It needs your age, weight, and height. There are two separate formulas for men and women: **For women â€“ BMR = 655.1 + (9.563 * weight in kg) + (1.850 * height in cm) – (4.676 * age)** . For men â€“ BMR = 66.5 + (13.75 * weight in kg) + (5.003 * height in cm) – (6.75 * age) .

**What is the formula q cv?**

Also, the more capacitance the capacitor possesses, the more charge will be forced in by a given voltage. This relation is described by the formula q=CV, where **Q is the charge stored, C is the capacitance, and V is the voltage applied**.

**How do you calculate how much heat is released or absorbed?**

To calculate the amount of heat released in a chemical reaction, use the equation **Q = mc Î”T**, 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 liquid (joule per kilogram degrees Celsius), and Î”T is the change in …

**How do you calculate heat gained by a solution?**

**Î”H = m Ã— Î”T Ã— S**

Î”H is the heat of solution, m is the mass of solvent, Î”T is the change in temperature, S is the specific heat of solvent.

**A unit of heat energy used in thermochemistry is the thermochemical calorie, equal to 4.184 joules**. It is commonly used as the unit for heat capacities, latent heats, and heats of reaction.

**How many calories is heat energy?**

Heat Energy

**One kilocalorie (1 kcal or 1000 calories) is the amount of heat (energy) needed to raise the temperature of one kg of water by one degree Celsius (Â°C)**. The SI standard unit for energy is Joule (J). One kcal is approximately 4.18 kJ (this varies slightly with temperature).

**How are calories and heat related?**

The Calorie Is a Unit of Energy

**A calorie is the amount of energy in the form of heat that is required to heat one gram of water one degree Celsius**. To measure the number of calories in a particular food substance, a certain amount of food is burned in a device called a calorimeter. As the food burns, heat is created.
