Heat which causes a change in temperature of substanceis called?
Heat which causes a change in temperature of substance is called specific heat.
What is the heat required to change the temperature of 1 gram of a substance?
The amount of heat needed to raise the temperature of 1 gram of a substance 1 degree celsius varies depending on the substance. This value is called the specific heat.
Difference between latent heat from sensible heat?
Two forms of heat are relevant in air conditioning:1. Sensible Heat2. Latent HeatSensible heatWhen an object is heated, its temperature rises as heat is added. The increase in heat is called sensible heat. Similarly, when heat is removed from an object and its temperature falls, the heat removed is also called sensible heat. Heat that causes a change in temperature in an object is called sensible heat.Latent heatAll pure substances in nature are able to change their state. Solids can become liquids (ice to water) and liquids can become gases (water to vapor) but changes such as these require the addition or removal of heat. The heat that causes these changes is called latent heat.Latent heat however, does not affect the temperature of a substance - for example, water remains at 100°C while boiling. The heat added to keep the water boiling is latent heat. Heat that causes a change of state with no change in temperature is called latent heat.Appreciating this difference is fundamental to understanding why refrigerant is used in cooling systems. It also explains why the terms 'total capacity' (sensible & latent heat) and 'sensible capacity' are used to define a unit's cooling capacity. During the cooling cycling, condensation forms within the unit due to the removal of latent heat from the air. Sensible capacity is the capacity required to lower the temperature and latent capacity is the capacity to remove the moisture from the air.
Difference between sensible heat and latent heat?
Sensible heat is heat supplied or taken away and causes an immediate change in temperature without changing the state. While latent heat is heat supplied or taken away and causes a change in state without change in temperature. This difference can be applied to the certain properties of water/steam. This is called the thermodynamics properties of steam.
What is the movement of thermal energy from a substance at a high temperature to a substance at a lower temperature called?
Heat
Heat which causes a change in temperature of substanceis called?
Heat which causes a change in temperature of substance is called specific heat.
Heat energy can change a liquid to a gas during a process called?
The process of heat causing a liquid to change to a gas is called evaporation. The heat increases the speed of the particles within the substance, making them expand and diverge. Once this occurs, the increased energy within the particles causes the substance to change stages into a gas.
What is the effect of temperature change to the amount of heat content of the substance?
The effect of temperature change to the amount of heat content of the substance is called heat transfer. As heat increases, the temperature decreases.
What causes a substance to change to gas?
The addition of heat or reduction in pressure can cause a substance to change from either a solid (sublimation) or liquid (evaporation) into a gas.
How much heat does it take to raise the temperature of a substance one degree?
The amount of heat required is called the specific sensible heat for the substance. Sensible, in this context, means something which can be sensed. This is in contrast to latent heat which is used to change the phase of a substance without a change in temperature.
What is the name of the energy needed to change a substance from a liquid to a gas?
The energy needed to change a substance from a liquid to a gas is called the enthalpy (or heat) of vaporization.
What is the heat required to change the temperature of 1 gram of a substance?
The amount of heat needed to raise the temperature of 1 gram of a substance 1 degree celsius varies depending on the substance. This value is called the specific heat.
A change of state in which energy is removed from a substance is called an?
A change of state where energy is removed from a substance is called an exothermic reaction. This chemical reaction releases energy in the form of light or heat.
What causes the liquid to change to a gas this process is called?
heat..high temperature.. this is called EVAPORATION.
How does the specific heat of a substance relate to temperature change?
A substance with a high specific heat will easily change temperature.
How does specific heat of a substance relate to temperature change?
A substance with a high specific heat will easily change temperature.
What is the name given to heat energy at melting point?
The heat energy required to change a substance between solid & liquid at constant temperature is called the "latent heat of fusion". If the change is from solid to liquid the substance gains this energy. If the change is from liquid to solid the substance gives up this energy. The exact amount of latent heat of fusion is different for different substances.
