Answer:
Their average kinetic energy increases
Explanation:
The average kinetic energy of the rice molecules increases as the pot is left on the cooking stove.
Heat is transferred to the pot by conduction from the heat source. The heat is then transferred to the rice in the cooking pot by convection.
- As the water in the pot heats up.
- The rice gains thermal energy.
- This causes the molecules of the rice particles to start vibrating.
- As the molecules vibrate about their fixed position, their thermal energy continues to increase.
- Therefore, the amount of heat absorbed by the rice increases with time and this actually cooks the food.
Answer:
Yes Concurred,but where is the question
B. It is the heat required to change a gram of substance from solid to liquid
Answer:
The answer to your question is: B
Explanation:
Physical properties are properties that occurs in matter but there is not change in the composition.
A. Solid ice can be very brittle. This is a physical property.
B. Water can form hydrogen and oxygen gas under electrolysis conditions. Here there is a change in the composition of matter, this is an example of chemical property
C. Water can freeze solid at 32 degrees Fahrenheit.
This is a physical property.
D. Liquid water can turn into steam in a heated tea kettle. This is a physical property
E. none of the above This option is wrong because option B is correct.
This heat is then distributed throughout your house via the duct system. ... Uneven air flow, and subsequently uneven heating in your home, can be caused when one or more components of the heating and air conditioning system are not working properly.
