Energy
The answer is mass. The Law of Conservation of Mass states that when a chemical or physical change takes place, you end up with the same amount of mass that you started in. It may just be in a different state, such as a gas.
Yes. In a way, energy and mass are closely related; energy HAS mass, mass HAS energy. Energy gets converted into mass routinely in particle accelerators. The kinetic energy from the moving particles gets converted into new particles.
No, mass and energy are not scalars. Mass is a scalar quantity while energy is a scalar quantity.
No. Sound is mechanical energy. Mechanical energy does not have mass. And no form of energy has mass. But energy has a mass equivalent per E=mc2 thanks to Albert Einstein.
Energy hasn't a color.
Mass and energy are related through Einstein's famous equation, Emc2. This equation shows that mass can be converted into energy and vice versa. When energy is added to a system, the mass of that system can increase, and when energy is removed, the mass can decrease. This relationship between mass and energy is a fundamental concept in physics.
Um... yes? Light is a form of energy. Energy has mass.
The total mass and energy in the universe are considered constant according to the law of conservation of mass-energy. While mass can be converted to energy and vice versa, the total amount remains the same. This principle is a fundamental concept in physics.
they have mass
No. Mass and kinetic energy are not the same thing.
According to the principle of mass-energy equivalence (E=mc^2), energy and mass are interchangeable. In theory, energy can be created without mass, such as in the case of virtual particles popping in and out of existence in quantum mechanics. These particles have energy but no permanent mass.
The energy primarily involved in lifting a heavy mass is gravitational potential energy. When you lift the mass against the force of gravity, you are increasing its potential energy, which can later be converted into kinetic energy if the mass is dropped.
