...........................................Yes this is true
The volume will be 2.25 L.
<u>Explanation:</u>
As per Charle's law, the volume of a gaseous system is directly proportional to the temperature provided the system is at constant pressure. Since volume of gas is directly proportional to the temperature of the gas molecules, V∝ T
So, in case there is a change in temperature with constant pressure, then there will be equal change in volume.

Thus, here
= 4.50 L ,
= 20 °C and
=
= 203 k Pa ,
= 10°C.
Since, volume and temperature is directly proportional then there will be increase in volume with increase in temperature and vice versa.


So, the new volume is 2.25 L.
The answer is ice. Nice brain teaser!
Answer : The specific heat of metal in this case will be 0.411 J/<span>g°C
Explanation : Specific heat can be calculated by using the formula
Q = Cm</span>ΔT
where Q is heat added which is 100 here
C is specific heat which needs to be found
m is mass of the metal
and ΔT is the temperature change
on substituting we get,
100 = x . 60 . 4.05
so, x = 0.411
