How does a substance gain heat?
A substance gains heat, or otherwise known as thermal energy, in many different ways. These can be from pressure, friction, the transformation of chemical energy to thermal energy, the transformation of electromagnetic energy to thermal energy, potential energy to the energy of motion (kinetic energy) or a substance can become exothermic during, and after a chemical change if the amount of energy produced from the broken bonds is greater than the amount of energy required for rearranged bonds to be made.
Change from liquid to a gas?
The process of a liquid turning into gas is called evaporation. This is when the particles in the liquid gain heat energy and diffuse off as a gas form.
What happens to energy in a substance when i change state?
As energy is absorbed, the energy moves up to other electron shell levels, but as the energy is released, it goes back to zero (ground state) and the energy is given off as light.
Why evaporation increase with the increase of temperaturein short answer?
The movement of the molecules increase with the temperature and more and more molecules gain more energy and can escape from the liquid and are transformed in gas.
How can energy be conserved if a substance must gain or lose thermal energy to change state?
Heat is a form of energy. It is just being transferred to the temperature bath (air, water, whatever). It hasn't been destroyed.
During which process does water gain the most heat energy?
Evaporation because it requires 2,260 Joules to gain heat energy. Condensation, freezing, and melting require less Joules than evaporation.
Do molecules gain or lose energy from evaporation?
Water molecules gain energy in order to vaporize. That additional energy is needed in order for the water molecules to overcome the attraction that they have for the other water molecules in the liquid that they are part of. In the gas phase, water molecules move independently of each other and are not connected as they are in the liquid state.
What happen during evaporation?
How about you have a look at the bottom of this page! It's been answered many times! :)
Does a substance gain energy when it freezes?
Lose
How does a substance gain thermal energy?
substances can gain thermal energy by heating them or applying electric shocks
What happens to substance during changed between liquid and gas?
The particles of the substance gain kinetic energy as they absorb heat energy. Eventually there is enough kinetic energy for the particles to escape the liquid phase, forming the gas phase.
What happens to substance during changes between gas to liquid?
The particles of the substance gain kinetic energy as they absorb heat energy. Eventually there is enough kinetic energy for the particles to escape the liquid phase, forming the gas phase.
Where in the water cycle does water vapor gain energy?
Water gains energy in evaporation to become water vapour.
When a substance changes from a solid to a gas it needs to what energy?
gain heat energy.
What causes the particles of a substance to evaporate?
The paticles gain energy.
Does vaporization lose or gain energy?
Vaporatization gains energy because it is the opposite of evaporation and evaporation loses energy. Here are some other things that, like vaporation, gain energy: -melting ... ... ... ... wait one minute, let me think again... oh ya now i remember... -nothing else :D
What happens to molecules when a substance evaporates?
When water molecules at the surface gain sufficient energy they can escape in the atmosphere. Evaporation (not vaporization) occur at any temperature; a higher temperature increase the rate of evaporation. The energy of water molecules increase by a temperature increase and some molecules at the surface can escape in the atmosphere.
