This process is called deposition.
<span>The correct answer is option A. i.e. Renewable source.
Using biofuels instead of fossil fuels because biofuels are renewable is am an example of Renewable sources. Biofuel is mainly developed from trees matter - leaves or decayed parts. And trees can be regrown and reused again So, it is a renewable source.</span>
Answer:
c. CaI_2 calcium iodide.
Explanation:
It is a common rule that vapor pressure is inversely proportional to boiling point of the substance. That is larger the boiling point smaller will be the vapor pressure.
B.P. of Ar= -185.8 °C
B.P. of CO2= -78.46 °C
B.P. of calcium iodide= 1,100 °C
B.P. of BF3 = -100.3 °C
B.P. of PF5= −84.6 °C
clearly, Boiling point of calcium iodide is highest hence, its vapor pressure is least among all the options.
