What else can I help you with?
What happens to the temp of a cup of coffee when a sugar cube is added. Does the temperature increase or decrease and why?
decrease,because the cube of sugar absorb some heat
Do you need to increase or decrease the amount of heat energy to change a solid to a liquid?
Thermal (heat) energy must be added or removed in order to cause a change of state.
When heat is added to a situation what 3 things happen?
- the volume increase- the density decrease- a chemical reaction may occur- a change of phase is possible
Due to heat would the resistance in non-ohmic material decrease or increase?
Increase
How does the density of air increase or decrease?
By Removing or addng heat
Does an increased rate of metabolism decrease the output of heat?
no even it will increase the out put heat
Why does the temperature increase reach maximum and then decrease?
The temperature increase reaching a maximum and then decreasing is due to the balance between heat input and heat loss. As heat is added, the temperature rises until it reaches a point where heat loss through various processes (like radiation, conduction, and convection) becomes greater than the heat input, causing the temperature to decrease. This balance results in a peak temperature before it starts to decline.
What indicates that energy has been added to or removed as heat or work from system?
An increase in temperature indicates that energy has been added as heat to a system, while a decrease in temperature indicates that energy has been removed as heat. Additionally, changes in volume or pressure can indicate that work has been done on or by the system.
How can you increase the velosity of honey?
To increase you make the honey colder and to decrease you heat the honey up
How do you higher the thermal efficiency of a cycle?
To increase the thermal efficiency of a cycle, you can: increase the temperature at which heat is added, decrease the temperature at which heat is rejected, and reduce internal irreversibilities and losses in the system. This can be achieved by optimizing the design, improving insulation, and using more efficient components.
As heat energy is added to a liquid do the particles increase or decrease in movement?
As heat energy is supplied to a liquid, its temperature rises. The rise of temperature causes a rise in the kinetic energy of the particles; which happens when the speed of the particles increases.
Does heat increase or decrease thermal energy?
Heat increases thermal energy by transferring energy to a system, causing the particles in the system to move faster and increase their kinetic energy, which in turn raises the system's overall thermal energy.
