Answer:
=745 Kelvin
Explanation:
- According to the pressure law the relationship between the pressure and absolute temperature of a gas at a constant volume is directly proportional.
- An increase in temperature causes a corresponding increase in pressure at a constant volume.
That is;
Mathematically;
When there are two varying conditions;
In this case;
P1 = 0.8 atm
T1 = 25+273 = 298 K
P2 =2.00 atm
T2= ?
Therefore;
Therefore, the temperature can be raised up to 745 kelvin without bursting vessel.
To find the weight of the gas you need to find the number of moles of using ideal gas formula. Remember to change the temperature unit to Kelvin and the pressure to kpa or atm
PV=nRT
n= PV/RT
n= 699 mmHg* 0.1333kpa * 0.357 L/ 8.314 kpa*L / mol*K * (45 +273.15)K
n=<span>0.012 moles
</span>
weight= n * molecular weight
weght= 0.012 *92.448 g/mol= 1.109 grams

Answer:
The statement that describes the advantage of a nonrenewable energy source is that ' they are currently found in abundance' Option D.
Explanation:
Nonrenewable energy sources are sources of energy which will not be replenished after their use, their production usually takes millions of years to be accomplished, Like crude oil, the synthesis under the ground was believed to take Millenium from the various geothermic reactions that occur on the buried biomass millions of years ago.
However, since these energy sources are liable to be exhausted quickly due to their unreplenish nature, nature provides them in abundance. They are currently found in large quantity. Take for example, the coal deposit and crude oil wells which had been mined for many years before now. The continuous usage of these nonrenewable sources nevertheless makes them to be susceptible to exhaustion in some years to come.
