Answer:
Explanation:
Given
Temperature of Room 
Area of Person 
Temperature of skin 
Heat transfer coefficient 
Emissivity of the skin and clothes 
Total rate of heat transfer=heat Transfer due to Radiation +heat transfer through convection
Heat transfer due radiation 
where 
Heat Transfer due to convection is given by
In my opinion it does. The more water the pot holds, the longer you need to wait for it to freeze. Since there is more water, some parts may not be completely frozen. An experiment you can try is to get an ice cube container and a pot. fill both of them and put them in the freezer for the same amount of time. When you take it out, the ice cubes should be frozen leaving the pot with cold water.
Answer:
Thermal energy of an isolated system changes with time If the mechanical energy of that system is constant according to the first law of thermodynamics, which states that thermal energy of an isolated system can still change as long as the total energy of that system does not change.
Explanation:
Answer:
No they are totally different...
Velocity is displacement/time. while vector is both magnitude and direction.....
Velocity is a vector quantity because it has both magnitude and direction
