C. FLOOD STAGE is reached when the water level of a stream or river exceeds its natural banks.
Flood stage is a level at which a body of water's surface has risen to a sufficient level to cause sufficient inundation in areas that are not normally covered by water, causing inconvenience or a threat to life and/or property.
It depends if you are taking the class in high school or college. For college doing the experiments is fun but the calculations is not. Also if you are taking it, bring friends.
Answer:
This process, which is the opposite of vaporization, is called condensation. As a gas condenses to a liquid, it releases the thermal energy it absorbed to become a gas. During this process, the temperature of the substance does not change. The decrease in energy changes the arrangement of particles.
STP condition mean we have P=1 atm. T=273K. R=ideal gas constant, but make sure you use the one that has the same units of pressure, temperature that you are using. In this case R=0.0821 L*atm K^-1mol^1. You are provided with n=2.1 moles.
V=nRTP
Input your values and solve.
