Question

Fill in the blanks

  According  to  the  principle  of  method  of  mixture,  the  net  heat  lost  by  the  hot
bodies  is  equal  to  _______  by  the  cold  bodies.
The  sultriness  in  summer  days  is  due  to  _______.
  ________  is  used  as  coolant.
  Ice  floats  on  water  becomes  ________.
Freezing  of  water  takes  place  at  ________  temperature  and  normal  pressure.

  On  freezing  volume  of  the  water  _______.
Temperature  of  a  body  is  directly  proportional  to  _________

Answer 1

According to the principle of method of mixture, the net heat lost by the hot
bodies is equal to net heat gained by the cold bodies. 
The sultriness in summer days is due to humidity. 
Water is used as coolant. 
Ice floats on water because of low density..
Freezing of water takes place at low temperature and normal pressure.

On freezing volume of the water increases. 
Temperature of a body is directly proportional to heat.


Hope it helps :)


Good day!

Answer 2

net heat gained, humidity, water, less density, zero degrees, expands, average kinetic energy.
