Answer:
I don't know about the oil part but "It is important to develop alternative
sources of energy because scientists are unsure of how long they will last"
Explanation:
Because they are nonrenewable resources, it takes hundreds to millions of years for them to be made again naturally. Once we're out, we're out. It would be a huge issue of that happened because Oil, Petroleum, and Natural Gas (all fossil fuels) are needed for heating, gas stoves, etc.
Answer:
A-Solid
Explanation:
Waves travel faster in solids & slowest in gases
Answer:
when a substance is cool the particles in the substance contracts, but when heated the particles expand and pressure becomes high that way the particles tend to move faster in the container, in other to escape.
Answer:
Risk management
Explanation:
Risk communication is exchange of the advice, real-time information and the opinions between the experts and the people which are facing threats to their economic, health, or well-being.
Risk assessment is overall process where the hazards and the risk factors which have potential to cause the harm is identified.
Risk perception is subjective judgement which people/ experts make about characteristics and the severity of the risk.
Risk management is evaluation, identification and prioritization of the risks followed by the coordinated and the economical application of the resources to monitor, minimize and control probability of the unfortunate events.
Thus, Option D is correct because in risk management, a Quantitative Solution is given to decrease risk level like to recycle the plastic.
<span>Charles law states that volume of a gas is directly proportional to temperature at constant pressure for a fixed amount of gas. the pressure at given conditions is 1.00 atm and the standard pressure at STP conditions too is 1.00 atm therefore pressure remains constant.
V1/T1 = V2/T2
the parameters for the first instance are on the left side and parameters at STP are on the right side of the equation.
T1 - temperature in kelvin - 273 + 30.0 </span>°C <span>= 303 K
T2 - standard temperature - 273 K
V1 - volume - 50.0 L
substituting the values in the equation
50.0 L / 303 K = V / 273 K V = 45.0 L
answer is 2) 45.0 L </span>
