P1V1=P2V2
100mL•500 mmHg=V2•1000mmHg
50000=V2•1000mmHg
50000/1000mmHg=V2
V2=50mL

<u>Answer:</u> The final temperature of water is 38.5°C
<u>Explanation:</u>
To calculate the amount of heat released or absorbed, we use the equation:
where,
q = heat absorbed = 1.506 kJ = 1506 J (Conversion factor: 1 kJ = 1000 J)
m = mass of water = 30 g
c = specific heat capacity of water = 4.184 Jl/g.°C
= change in temperature =
Putting values in above equation, we get:
Hence, the final temperature of water is 38.5°C
Given:
114.32g of water
14.85oC is raised
to 18.00oC
Required:
Change in heat
energy
Solution:
This can be solved
through the equation H = mCpT
where H is the heat, m is the mass, Cp is the specific heat and T is the change in temperature.
The specific heat
of the water is 4.18 J/g-K
Plugging in the
values into the equation
H = mCpT
H = (114.32g) (4.18
J/g °C) (18 – 14.85)
H = 1,505.3 J
