According to zeroth law of thermodynamics, when two objects are kept in contact, heat (energy) is transferred from one to the other until they reach the same temperature (are in thermal equilibrium). When the objects are at the same temperature there is no heat transfer.
So, at equilibrium, =
,
+
q=m×c×T, where q = heat energy, m = mass of a substance, c = specific heat (units J/kg∙K), T is temperature
=(15X13X4.19)+(148X88.3X4.19)
= 81.37 ° C
Answer:
<h3>The answer is 400 mL</h3>Explanation:
The new volume can be found by using the formula for Boyle's law which is
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
Since we are finding the new volume
So we have
We have the final answer as
<h3>400 mL</h3>Hope this helps you
Answer: The partial pressure of the water vapor is 1.108 atm
Explanation:
According to Dalton's law, the total pressure of a mixture of gases is the sum of individual pressures exerted by the constituent gases.
Thus
Given: =4.015 atm
= 2.907 atm
= ?
Thus
Thus the partial pressure of the water vapor is 1.108 atm
