A bag of potato chips is sealed in a factory near sea level. The atmospheric pressure at the factory is
1 answer:
Answer: The pressure inside the bag of potato chips in Pascal's is 109
Explanation:
Pressure of the gas is defined as the force exerted by the particles on the walls of the container. S.I unit of pressure is pascal.
Thus units of pressure can be mm Hg or atmosphere or bar or Pascal.
Given : Pressure inside the bag is the same as atmospheric pressure at the factory = 0.82 mmHg
Pressure 760 mm Hg = 101325 Pa
0.82 mm Hg =
Thus the pressure inside the bag of potato chips in Pascal's is 109

<u>Answer:</u> The amount of energy required to raise the given amount of temperature is 6400 J
<u>Explanation:</u>
To calculate the heat absorbed by the lead, we use the equation:
where,
q = heat absorbed
m = mass of lead = 200 g
c = heat capacity of lead = 0.128 J/g°C
= change in temperature = 250°C
Putting values in above equation, we get:
Hence, the amount of energy required to raise the given amount of temperature is 6400 J
