It reduces in size by half.
This is due to Charles's law, which states that the absolute temperature and volume of a gas are directly proportional, given that pressure is kept constant. Therefore, if the absolute temperature is halved, the volume of the gas will also halve.
Clouds are made of water. When water evaporates it turns into clouds. So, I think the answer is EVAPORATED water.
K⁺ has positive charge, the easiest way to form a bond is to connect to negatively charged ion. We have only one negative ion Cl⁻.
So, the answer is
C. Cl⁻.
The age of the remnants is calculated as 3807 years.
<h3>What is the half life?</h3>
The half life is the time taken for only half of the number of the radioactive atoms to remain.
Half life of carbon - 14 = 5730 years.
Initial count rate = 8.0 counts per minute per gram
Count rate at time t = 12.7 counts per minute per gram of carbon
Since;
0.693/t1/2 =2.303/t log (N/No)
0.693/5730 = 2.303/t log (12.7/8)
1.21 * 10^-4 = 2.303/t * 0.2
t = 2.303 * 0.2/1.21 * 10^-4
t = 0.4606/1.21 * 10^-4
t = 3807 years
