Why does a chocolate bar become soft beside an oven?
Heat transfer. The oven is warmer than the chocolate bar, which is solid at room temperature. The difference in temperature means that heat will transfer from the warmer oven to the chocolate bar. Chocolate melts at ~36*C, so if enough energy is added to the chocolate, the temperature will rise until it reaches 36*C and begins to melt.
What is the transfer of thermal energy from an object of higher temperature to an object of lower temperature?
The increase in the kinetic energy of a material's particles from an object of higher temperature to one of lower temperature is known as heat transference.heat
Does juice temperature increase with increasing convective heat transfer coefficient at any constant kettle surface temperature?
Yes, the juice temperature increases with an increasing convective heat transfer coefficient at any constant kettle surface temperature. The convective heat transfer coefficient represents the efficiency of heat transfer from the kettle to the juice. As the convective heat transfer coefficient rises, more heat is transferred from the kettle surface to the juice per unit of time. This increased efficiency results in a faster temperature rise in the juice. Therefore, a higher convective heat transfer coefficient enhances the overall heating process, leading to a greater temperature increase in the juice even when the kettle surface temperature remains constant.
How do you put microwave in a sentence?

What heat transfer uses electromagnetic waves to increase thermal energy?
Microwave Radiation is Very Effectively absorbed by Water molecules, this results in the increased thermal agitation of the Water molecules that absorb the Mw radiation - as found in Microwave ovens.
What has a maximum transfer rate of 150 Mbps?
Microwave Radio
What transfer of energy by movement of fluids or gases with different temperatures is called?
pressure increase causes temperature increase temperature increase causes pressure increase when volume is constant that's Boyle's law if the temperature increases the speed of the molecules increase and the number of collisions increases . different slant on the same thing i guess. Brown usually Brownian motion.
What is the relationship between energy transfer and temperature change?
energy transfer increases temperature
What causes the transfer of thermal energy?
Thermal energy transfer from high temperature to low temperature. The cause of transfer is the temperature difference.
What are the ratings and certificates for The Gruen Transfer - 2008 Chocolate 1-4?
The Gruen Transfer - 2008 Chocolate 1-4 is rated/received certificates of: Australia:M
What energy transfer takes place with a microwave?
In a microwave oven, energy is transferred from the emitter (which is technically a klystron) to the water molecules in the item being heated, which have a resonant frequency equal to that of the microwave emission.
How does eddy current loss effect a transformer?
Eddy currents act to increase the temperature of a transformer's core above ambient temperature, resulting in a loss of energy through heat transfer -thus reducing its efficiency.
