Wires with high resistance change electrical energy into what?

Wires with high resistance change electrical energy into heat energy. This occurs due to the resistance in the wire hindering the flow of electrons, causing them to collide and generate heat.


How resistance varies with the change in temperature?

Heat Capacity


Do all substances change when heat is added?

yes but only if you heat it enough


Does heat change all substances?

It depends on what change this is. If this is visible change, it may not be detected. Otherwise, heat does change substances in terms of kinetic energy of molecules in a body or average distance between the molecules of the body.


What is unwanted heat loss called in electricity?

Unwanted heat loss in electricity is called resistive loss or I2R loss, where I represents the current flowing through a device and R represents the resistance of the device. This type of energy loss occurs as heat when electrical current passes through a conductor with resistance.


How could you change the resistance of the thermistor?

You can modify the resistance of a thermistor by changing its temperature. As the temperature increases, the resistance of a thermistor decreases, and vice versa. By adjusting the surrounding temperature or applying heat or cooling, you can effectively change the resistance of the thermistor.


What is the relationship between the heat of reaction and the heat of formation in a chemical reaction?

The heat of reaction is the difference between the heat of formation of products and reactants in a chemical reaction. It represents the amount of heat released or absorbed during the reaction. The heat of formation is the heat change when one mole of a compound is formed from its elements in their standard states. The relationship between the two is that the heat of reaction is related to the heat of formation of the substances involved in the reaction.


What is the specific heat of mixture and how does it affect the overall temperature change in a system?

The specific heat of a mixture is the amount of heat needed to raise the temperature of the mixture by 1 degree Celsius. It affects the overall temperature change in a system because substances with higher specific heat require more heat to raise their temperature, while substances with lower specific heat require less heat. This means that the specific heat of a mixture determines how much heat is needed to change its temperature, impacting the overall temperature change in the system.


Why same amount of heat supplied to same amount of different substances does not produce the same increase in temperature?

There is a formula in physics ΔQ=m*c*ΔT, where m is the mass of the substance you are heating, ΔQ is the heat you supply to the substance, c is the specific heat which has a different value for different substances and ΔT is the change in temperature. If your substances are different and they have the same mass then by supplying the same amount of heat the change in temperature will be different.


Do acids melt substances?

No, melting is a change of state caused by heat. Acids are corrosives.


What equation represents the energy it takes to heat a sunstance?

The equation that represents the energy required to heat a substance is Q = mcΔT, where Q is the heat energy, m is the mass of the substance, c is the specific heat capacity of the substance, and ΔT is the change in temperature.
