1.Liquids only exert pressure downward.
noname [10]

1. Liquids and gases exert pressure in all directions. Hence, the statement is false.

2. As the depth of liquid increases, so does the pressure. Hence, the statement is true.

3. Pascal's principle states that applied pressure will be transmitted throughout a fluid. Hence, statement C is true.

4. The pressure in a fluid depends only on the depth from the surface and not on the shape of the container. Hence, the statement is false.

5. Archimedes' principle involves buoyancy. Hence, statement C is true.

6. The temperature at which water boils can't be related to the weather. Hence, the statement is false.

7. A barometer is a scientific instrument used to measure atmospheric pressure, also called barometric pressure. Hence, the statement is false.

<h3>What is a barometer?</h3>

A barometer is an instrument used to measure air pressure.

1. Since a fluid has no definite shape, its pressure applies in all directions. Liquids and gases exert pressure in all directions. Hence, the B is true.

2. Pressure increases as the depth increase. The pressure in a liquid is due to the weight of the column of water above. Since the particles in a liquid are tightly packed, this pressure acts in all directions.

3. Pascal's law says that pressure applied to an enclosed fluid will be transmitted without a change in magnitude to every point of the fluid and to the walls of the container. The pressure at any point in the fluid is equal in all directions.

4. The pressure in a fluid depends only on the depth from the surface and not on the shape of the container.

5. Archimedes' principle states that a body immersed in a fluid is subjected to an upwards force equal to the weight of the displaced fluid.

6. Boiling occurs when the vapour pressure reaches or exceeds the surrounding pressure from the atmosphere or whatever else is in contact with the liquid. At standard atmospheric pressure (1 atmosphere = 0.101325 MPa), water boils at approximately 100 degrees Celsius.

A hot air balloon is filled with 15 moles helium gas and 5 moles nitrogen gas. What is the volume of the balloon at 1.01 atm and
kvasek [131]

<u>Given:</u>

Moles of He = 15

Moles of N2 = 5

Pressure (P) = 1.01 atm

Temperature (T) = 300 K

<u>To determine:</u>

The volume (V) of the balloon

<u>Explanation:</u>

From the ideal gas law:

PV = nRT

where P = pressure of the gas

V = volume

n = number of moles of the gas

T = temperature

R = gas constant = 0.0821 L-atm/mol-K

In this case we have:-

n(total) = 15 + 5 = 20 moles

P = 1.01 atm and T = 300K

V = nRT/P = 20 moles * 0.0821 L-atm/mol-K * 300 K/1.01 atm = 487.7 L

Ans: Volume of the balloon is around 488 L
