What else can I help you with?
When does the addition of heat to a substance not result in a temperature increase?
-- When the heat causes the substance to melt or vaporize. -- When heat is being leaked out of the substance at the same rate somewhere else.
Define the heat of neutralization?
Heat of neutralization describes one of the effects of mixing a base with an equally strong acid. This neutralizes the substance, which changes the substance's heat as a result.
Sensible heat involves a change in a substance's?
Sensible heat involves a change in a substance's temperature without a change in its phase. It is the heat exchange that causes a change in the temperature of a substance but does not result in a change of state (solid, liquid, gas).
What theory did brown suggest to explain the nature of heat?
Brown suggested the kinetic theory of heat to explain the nature of heat. This theory proposes that heat is the result of the movement of particles in a substance, and that as particles move faster, the substance's temperature increases.
What state will most likely result if heat is added to a liquid?
It will change into a gas.Adding heat to or removing heat from a system may result in a temperature change and possibly a change of state. A liquid substance needs heat added to it in order to enter a gaseous state. If enough heat is added to a liquid substance it will change into a gas.
What is the effect when you apply heat to substance?
When heat is applied to a substance, it causes the molecules in the substance to gain energy and move faster, leading to an increase in temperature. This can result in phase changes, such as melting or boiling, depending on the substance. In chemical reactions, heat can also provide the activation energy needed for the reaction to occur.
What occurs to the particles in a substance at low temperature when energy is transferred to the substance as heat?
At low temperatures, the particles in a substance are in a relatively low-energy state and move slowly, often vibrating in place. When energy is transferred to the substance as heat, the particles absorb this energy, causing them to gain kinetic energy. As a result, their motion increases, leading to greater vibration or movement, which can ultimately result in a phase change, such as melting if the substance is solid.
How does increasing the heat energy of a substance change the behavior of particles of the substance?
Increasing the heat energy of a substance causes the particles to move faster and have more kinetic energy. This can lead to an increase in the substance's temperature, change in state (solid to liquid to gas), or possibly result in chemical reactions depending on the substance.
Why does the matter expand when heated?
Heat energy causes all matter to expand, a reason for this strange occurrence is that when a particular substance receives heat whether it be through conduction, convection or radiation the atoms inside the substance become more energised therefor needing more space to move, they push the outside boundaries making the substance expand. If the substance receives an exceeding amount of heat energy it will change states of matter.
If you were trying to find a substance that increases in temperature rapidly you should choose a substance with?
A substance with a low heat capacity.A substance with a low heat capacity.A substance with a low heat capacity.A substance with a low heat capacity.
What is the meaning of heat energy in science?
Heat energy is a form of energy that results from the movement of particles within a substance. It is transferred between objects with different temperatures as a result of this particle movement. The higher the temperature of an object or substance, the greater the amount of heat energy it contains.
What does the specific heat of a substance?
The ability of a substance to hold heat.
