1 Answer. Boiling water is an endothermic process, which supplies heat to the water molecules, increasing their potential energy. The applied heat causes the water molecules to move further away from each other without causing any increase in overall temperature.
What type of energy is boiling water?
Boiling water on a stove is an example of thermal energy. Thermal energy is produced when the atoms and molecules in a substance vibrate faster due to a rise in temperature.
Is boiling water mechanical energy?
Energy is needed to carry out processes, such as boiling water or burning candles. … Energy has many forms, such as light, heat, electricity, chemical energy (stored in chemical bonds) and mechanical energy (moving matter, such as flowing water).
What is energy required for the boiling process?
Why is energy required for the boiling process? The more energy obtained by heat allows molecules to move faster and eventually separate from other liquid molecules to boil and form a gas. … Heat is lost.
What type of energy is food?
Food energy is chemical energy that animals (including humans) derive from their food and molecular oxygen through the process of cellular respiration.
What type of energy is lightning?
As the charges that cause the energy are moving, electrical energy is a form of kinetic energy. Lightning, batteries and even electric eels are examples of electrical energy in action!
Does water create energy in the body?
Even though it contains no calorie content, water is the medium for most chemical reactions in the body, especially those metabolic reactions involved in energy production. The body uses water as a coolant, helping to regulate body temperature during exercise, fever and in hot environments.
What type of energy is climbing stairs?
A person who has climbed to the top of a flight of stairs has transferred chemical energy stored in their muscles to the gravitational potential energy (GPE) they have when standing at the top.
Is Food potential energy?
Food contains chemical potential energy – as our bodies digest it, the stored energy is converted into energy for us to move and grow.
How much energy is required to boil 150g water?
25 degrees Celsius is 298 degrees Kelvin; 100 degrees Celsius, 373 degrees Kelvin. = 150 g x 4.184 J/g/K x (373 – 298) K = 47,070 J. Thus, 47,070 J are needed to increase the temperature of 150 g of water from 25 degrees C to its boiling point of 100 degrees C.
Why does boiling require more energy than melting?
Much more energy is required to change the state from a liquid to a gas than from a solid to a liquid. This is because of the large separation of the particles in the gas state. The values of the heats of fusion and vaporization are related to the strength of the intermolecular forces.
What happens to energy when water boils?
For instance, when water is boiling, adding heat does not increase its temperature. This happens at the boiling temperature of every substance that can vaporize. … When energy is added to a liquid at the boiling temperature, its converts the liquid into a gas at the same temperature.
What 4 types of energy does the body use or create?
In the body, thermal energy helps us to maintain a constant body temperature, mechanical energy helps us to move, and electrical energy sends nerve impulses and fires signals to and from our brains. Energy is stored in foods and in the body as chemical energy.
What are the 2 main forms of energy?
Many forms of energy exist, but they all fall into two basic categories:
- Potential energy.
- Kinetic energy.

Which part of body consumes most energy?
It is well established that the brain uses more energy than any other human organ, accounting for up to 20 percent of the body’s total haul. Until now, most scientists believed that it used the bulk of that energy to fuel electrical impulses that neurons employ to communicate with one another.
