Answer:
The final temperature = 848.7 K or 575.7 °C
Explanation:
Step 1: Data given
Temperature = 25.0 °C = 298 K
Volume = 158 mL = 0.158 L
The volume increases to 450 mL = 0.450 L
The pressure is constant
Step 2: Calculate the final temperature
V1/T1 = V2/T2
⇒with V1 = the initial volume = 0.158 L
⇒with T1 = the initial temperature = 298 K
⇒with V2 = the increased volume = 0.450 L
⇒with T2 = the new temperature = TO BE DETERMINED
0.158 L / 298 K = 0.450 L / T2
T2 = 0.450 L / (0.158L/298K)
T2 = 848.7 T
The final temperature = 848.7 K or 575.7 °C

Answer:
Option (D)
Explanation:
Oil (crude and petroleum) is one of the major resources on earth in which the economy of a country is largely dependent on. These are non-renewable resources, which take thousands to million years of years in order to form.
It is highly essential. Every day, a large quantity of oil is being consumed. According to the researches done in the year 2015, it has been observed that the average global consumption of oil was 95 million barrels each day.
It has a high demand, and so it is being regularly used, and it has also been predicted that the present global oil reserves would be highly exhausted within the next 50 years.
Thus, the correct answer is option (D).
