The Earth moves around the sun. A year is 365 days because that's how long it takes the Earth to go around one time. Seasons change depending on which part of the Earth is tilted closest to the sun. The sun is the source of nearly all the Earth's energy.

Temperature is____ to the average kinetic energy of a gas.
blsea [12.9K]

Answer: Option (b) is the correct answer.

Explanation:

As on increasing the temperature, the molecules gain more kinetic energy due to which they tend to collide and move rapidly from one place to another.  

Thus, we can conclude that when temperature is increased, the kinetic energy of the molecules increases. This means that temperature is directly proportional to the average kinetic energy of a gas.

A hydrogen atom has a radius of 2.5 x 10-11 m<br> Determine the radius of a magnesium atom.
baherus [9]

Answer:

R = 1.5* 10^{-10}m

Explanation:

Given

r = 2.5 * 10^{-11}m -- radius of hydrogen atom

<em>See attachment</em>

Required

Determine the radius of magnesium atom (R)

From the attachment, the ratio of a hydrogen atom to a magnesium atom is:

Ratio = 6mm : 36mm

Simplify

Ratio =1 : 6

Represent the radius as ratio:

Ratio = r : R

Substitute r = 2.5 * 10^{-11}m

Ratio = 2.5 * 10^{-11}m : R

Equate both ratios

2.5 * 10^{-11}m : R = 1 : 6

Express as fraction

\frac{2.5 * 10^{-11}m}{R} = \frac{1}{6}

Cross Multiply

R * 1 = 2.5 * 10^{-11}m * 6

R * 1 = 2.5 * 6* 10^{-11}m

R * 1 = 15* 10^{-11}m

R = 15* 10^{-11}m

R = 1.5*10* 10^{-11}m

R = 1.5* 10^{1-11}m

R = 1.5* 10^{-10}m

Hence, the radius of the magnesium atom is: 1.5* 10^{-10}m
