Answer:
A
Explanation:
Isotopes are atoms of the same element with the same number of protons and electrons but different numbers of neutrons.
Isotopes can also be defined as atoms of the same element with the same atomic number but different mass numbers e.g isotopes of chlorine, oxygen and so on.Oxygen for instance has three isotopes with the same atomic number,8 and different mass numbers,16,17 and 18.
<u>Residual soil and transported soil differ by as follows:</u>
Residual soil stays over its parent rock and transported soil forms from particles from another place.
<u>Explanation:</u>
Soil forms from weathering of rock. When a rocks get weathered it creates small paiticles. That forms different kind of soil. Soil varies in texture, structure, colour, composition and in pH level. Each and every soil type produced from parent rock. Depending upon the character of parent rock soil type is determined like basalt the igneous rock forms black soil.
Residual soil stays over parent rock it does not get off by the activities of natural agents like air, water, wind and glacier. Transported soil comes from hilly area to flat topped ground by transportation through some transporting agents of nature. It is immature soil.
Answer:
38.1 L
Explanation:
Data given:
initial volume V1 of a gas = 3 L
initial Temperature T1 of a gas = 21 °C
convert Temperature to Kelvin
T1 = °C +273
T1 = 21°C + 273 = 294 K
final Temperature T2 of a gas = 100°C
convert Temperature to Kelvin
T2 = °C +273
T2 = 100°C + 273 = 373 K
final Volume V2 of a gas = ?
Solution:
This problem will be solved by using Charles' law equation at constant pressure.
The formula used
V1 / T1 = V2 / T2
As we have to find out Volume, so rearrange the above equation
V2 = V1 x T2 / T1
Put value from the data given
V2 = 3 L x 373 K / 294 K
V2 = 38.1 L
So the final Volume of a gas = 38.1 L
The answer is d. more effective in liquids than in gases
