Okay I did the math and I'm guessing around 18*C
The correct answer is greenhouse gases. It is the most abundant gases among the choices in the atmosphere. These gases are water vapor, methane, nitrous oxide, ozone and carbon dioxide. Without these gases, the temperature of Earth will be about -18 degrees Celsius.
Answer:
P2 = 1250mmHg
Explanation:
V1 = 5.0L
P1 = 750mmHg
V2 = 3.0L
P2 = ?
According to Boyle's law, the volume of a fixed mass of gas is inversely proportional to its pressure provided that temperature remains constant.
P = k/V k = P*V
P1*V1 = P2*V2 = P3*V3 =........=Pn*Vn
P1 *V1 = P2 * V2
Solve for P2
P2 = (P1 * V1) / V2
P2 = (750 * 5.0) / 3.0
P2 = 3750 / 3
P2 = 1250mmHg
The final pressure of the gas is 1250mmHg
Answer:
The independent variable here is the types of soil
Explanation:
An independent variable is the variable that is not affected by the outcome of other variables in a given experiment. This variable is the variable that is intentionally altered/changed (directly or indirectly) by the researcher in order/expected to produce a result for the experiment. Thus, the independent variable here is the types of soil. This is because the soil was intentionally changed/varied by the researcher and it's expected to determine the heights of the bean plants grown.
