Answer:
<h2>The answer is 1.48 L</h2>Explanation:
In order to find the original volume we use the same 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 original volume
From the question
P1 = 172 kPa = 172000 Pa
P2 = 85 kPa = 85000 Pa
V2 = 3 L
We have
We have the final answer as
<h3>1.48 L</h3>Hope this helps you
<u>Answer:</u> The specific heat of metal is 2.34 J/g°C
<u>Explanation:</u>
To calculate the mass of water, we use the equation:
Density of water = 1 g/mL
Volume of water = 35 mL
Putting values in above equation, we get:
When metal is dipped in water, the amount of heat released by metal will be equal to the amount of heat absorbed by water.
The equation used to calculate heat released or absorbed follows:
......(1)
where,
q = heat absorbed or released
= mass of metal = 4.82 g
= mass of water = 35 g
= final temperature = 34.5°C
= initial temperature of metal = 115°C
= initial temperature of water = 28.7°C
= specific heat of metal = ?
= specific heat of water = 4.186 J/g°C
Putting values in equation 1, we get:
Hence, the specific heat of metal is 2.34 J/g°C
