Using Charles's law; which states that the volume of an ideal gas is directly proportional to the absolute temperature at constant pressure. 
That is; V α T
Hence; V1/T1 = V2/T2 = constant
V2 =  V1 × (T2/T1)
    = 250 × (350/300) = 291.67 mL
Therefore; the new volume will be 291.67 mL

<u>Answer:</u> The final volume of the system is 291.66 mL.

<u>Explanation:</u>

To calculate the final volume of the system, we use the equation given by Charles' Law.

This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

\frac{V_1}{T_1}=\frac{V_2}{T_2}

where,

V_1\text{ and }T_1 are the initial volume and temperature of the gas.

V_2\text{ and }T_2 are the final volume and temperature of the gas.

We are given:

V_1=250mL\\T_1=300K\\V_2=?mL\\T_2=350K

Putting values in above equation, we get:

\frac{250}{300K}=\frac{V_2}{350K}\\\\V_2=291.66mL

Hence, the final volume of the system is 291.66 mL.

Answer:

C. Tip had the lower pressure, it was 652.71mmHg

Explanation:

To answer this question you need to convert both values into a common unit so you can compare directly.

87kPa = 652.71 mmHg

What phase of matter has enough kinetic energy to partially overcome the intermolecular attraction between the particles, allowi
MatroZZZ [7]

Answer:

Liquid

Explanation:

It is liquid because liquid will always take shape of the container. For example, take a square container and a round cup, and a 1/d of water, put it in the square container and it will take the shape of that container, but take the SAME water and put it in the cup and now its in a circle cause it is taking shape.

What pressure is needed to reduce the volume of gases in a car’s cylinder from 48.0 cm3 at 102 kPa to 5.20 cm3?
k0ka [10]

Answer: The pressure that is needed is around 405kPa-755kPa

To summarize into 405PPM-755PPM

Explanation: In which 405 PPM-755 PPM which is about the same amount of pressure that water pressurises a car in water or a better example is that it's the same amount of pressure as if a penny was dropped from the sky towards a person holding a square piece of cardboard in which then the penny would directly go straight through the piece of cardboard.
