Increasing the temperature of gas in a container that cannot expand is a way to _______. decrease the volume of the gas decrease
alex41 [277]

Answer:

Increase the pressure of the gas

Explanation:

According to the Pressure law, for a fixed mass of gas, at a constant volume (V), the pressure (P) is directly proportional to the absolute temperature (T).

From the kinetic molecular theory, gases are composed of particles which are in constant motion, colliding with themselves as well as with the walls of their container.

When the temperature of these gas molecules is increased, the molecules acquire more kinetic energy and the rate of collisions increases. Since the container cannot expand, the increase in pressure is due to the increase in collisions between the molecules of the gas as well as with the walls of their container.

Density of iron is 7.8 g/cc. How much would 10 cc of iron weigh?
Elena-2011 [213]

Answer:

<h3>The answer is 78 g</h3>

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

<h3>mass = Density × volume</h3>

From the question

volume = 10 cc

density = 7.8 g/cc

So we have

mass = 7.8 × 10

We have the final answer as

<h3>78 g</h3>

Hope this helps you

How many milliliters of 0.02 M HCl are needed to react completely with 100 mL of 0.01 M NaOH?
serious [3.7K]
The reaction of HCl and NaOH is HCl + NaOH = NaCl + H2O. So the mole number of HCl and NaOH is equal. So the volume of HCl =0.01*0.1/0.02=0.05 L =50 ml. So the answer is D).
