Answer:

The particles move faster, and their average kinetic energy increases.

Explanation:

When the temperature of gases increases the reaction rates will increase. Molecules of gases will be furnished with higher kinetic energy. Kinetic energy is directly proportional to temperature. Increase in temperature causes the frequency of ordinary collisions and effective collisions per unit time to increase. This leads to a surge in kinetic energy too.

Answer: The particles move faster, and their average kinetic energy increases.

Explanation:

Kinetic energy is the energy possessed by an object by virtue of its motion.

Average kinetic energy is defined as the average of the kinetic energies of all the particles present in a system. It is determined by the equation:

$K=\frac{3RT}{2}$

K= kinetic energy

R= gas constant

T= temperature

From above, it is visible that kinetic energy is directly related to the temperature of the system.

So, if temperature is more, average kinetic energy of the system is more and thus speed of the molecules will be more.Thus the molecules will move faster.

A scientist fills a large, tightly sealed balloon with 75,000 mL of helium at STP.

pav-90 [236]

Considering the definition of STP conditions, 3.35 moles of helium are contained within the balloon.

<h3>Definition of STP condition</h3>

The STP conditions refer to the standard temperature and pressure. Pressure values at 1 atmosphere and temperature at 0 ° C are used and are reference values for gases. And in these conditions 1 mole of any gas occupies an approximate volume of 22.4 liters.

<h3>Amount of moles of helium within the balloon</h3>

In this case, you know that scientist fills a large, tightly sealed balloon with 75,000 mL of helium at STP.

So, you can apply the following rule of three: if by definition of STP conditions 22.4 liters are occupied by 1 mole of helium, 75 L (75 L= 75000 mL, being 1 L= 1000 L) are occupied by how many moles of helium?

$amount of moles of helium=\frac{75 Lx1 mole}{22.4 L}$
