What happens to a gas that is enclosed in a rigid container when the temperature of the gas is increased?

1 answer:

4 0

A. the gas particles move faster and collide more frequently, which causes an increase in pressure.

Increasing temperature increases the energy of the gas, which causes the kinetic energy of the molecules to increase.

If you are driving 90 km/hkm/h along a straight road and you look to the side for 2.8 ss , how far do you travel during this ina

pashok25 [27]

Answer:

Distance = 70 meters

Explanation:

Given the following data;

Speed = 90 km/h

Time = 2.8 seconds

Conversion:

90 km/h to meters per seconds = 90 * 1000/3600 = 90000/3600 = 25 m/s

To find the distance covered during this inattentive period;

Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.

Mathematically, speed is given by the formula;

$Speed = \frac{distance}{time}$

Making distance the subject of formula, we have;

$Distance = speed * time$

Substituting into the above formula, we have;

$Distance = 25 * 2.8$

Distance = 70 meters

What does it mean that a form of energy might take more energy to harness than it provides? Are renewable resources always renew

frez [133]

A form of energy might take more energy to harness than it provides because of dissipated energy. During the transformation process, not all of the energy will be converted to useful energy. Some of the energy are dissipated in the form of heat. Renewable resources are resources that are replenished at a faster rate than they are used. They become non-renewable when these resources are used up at a faster rate than they are replenished. We don't use renewable resources for everything that we use energy for because the energy transformation might be inefficient or requires a lot of capital and maintenance.
