Answer:
Explanation:
Using apparent = mass of liquid expelled/mass of liquid remaining × temp. rise
Mass expelled: 250-248.5=1.5g
Mass remaining =248.5g
Temp. rise= 60-30= 30ºc
= 1.5/248.5×30=0.0002012
Using real= apparent + cubic expansivty
Cubic= 3 × linear expansivty
= 3×0.000006=0.000018
0.0002012+0.000018=0.0002192
Hope it helps : )
Specific heat of air at constant pressure = 1.005KJ/kg-K Apparently the hot air leaves the house while equal quantity of the cool air passes inside (Neglecting the small specific volume changes between the hot and the cold air) So the situation can be sampled as a scenario where there is continuous draw down of the thermal energy from the air.
The answer is false..................
