When we pump the football the volume and pressure of its internal gases both increase at a time.Is this against the boyle's law?

Clearly, if we pump in air into the football, the given assumption is invalid. For a full bladder (or whatever they fill footballs with these days), with a given quantity of gas present, the would give a reasonable approximation of temperature, pressure, and volume.

A mixture of gases contains $"H"_2$ and $"O"_2$ gases in the ratio of $"1:4 w/w"$. What is the molar ratio of two gases in the mixture?

All you have to do here is to convert the mass ratio to a mole ratio by using the conversion factor that takes you from grams to moles or vice...

The gases in a hair spray can are at a temperature of 27 C and a pressure of 30 kPa. If the gases in the can reach a pressure 90 kPa, the can will explode. To what temperature must the gases be raised in order for the can to explode?

Since the volume is constant but the pressure and temperature are changing, this is an example of Gay-Lussac's Law: $color(blue)(bar(ul(|color(white)(a/a) p_1/T_1=p_2/T_2color(white)(a/a)|)))" "$ We can rearrange the...

How do Boyle's law and Charles' law differ?

Boyle's Law is an inverse relationship between pressure and volume. The kinetic theory of matter is fundamental to Boyle s Law. As the volume decreases the molecules collide more frequently...

How is Charles' law different from Boyle's law?

In volume and pressure vary inversely, whereas in , volume and pressure vary directly. Consider an example, if the pressure in Boyle's law is doubled from 1.0 atmospheres to 2.0...

How does Boyle's law relate to a bicycle pump?

simply describes the relationship between the pressure and volume of an enclosed gas when Temperature remains constant. That relationship, usually expressed as $P_1$ $V_1$ = $P_2$ $V_2$, just means...

Using boyle's law and your understanding of what is happening at the particle level, explain why the pressure increases in aclosed water bottle as you squeeze it?

Boyle's law relates volume to pressure. As volume decreases pressure increase. In the case of the example, squeezing the bottle reduces the volume. On a particle level, the number of...

Why boyle's law is not possible in low temperature and high pressure?

Under conditions of low temperature, gases, all real gases, condense to give liquids. Under conditions of high pressure, the same condition obtains. Under moderate pressures and moderate to high temperatures,...

What do Boyle's law and Charles's law have in common? How are they different?

tells us that for an ideal gas, at a constant temperature, volume is proportional to pressure. So doubling the volume, halves the pressure, providing temperature is kept the same....

What is the relationship between pressure and volume in Boyle's Law?

According to the : $PV//T=PV//T$ This is just the general formula, and is derived from it. Boyle's Law says that temperature is constant. So, we can remove temperature from the...

A small research submarine with a volume of 1.2x10 ^5 L has an internal pressure of 1.0 atm and an internal temperature of 150°C. If the submarine descends to a depth where the pressure is 150 atm and the temperature is 30°C, what will the volume of the gas inside be if the hull of the submarine breaks?

The answer is $573L$. The best way to approach this problem is by using the $(P_1V_1)/T_1 = (P_2V_2)/T_2$, which relates temperature, pressure, and volume, assuming the number of remains...
