Answer:
T=833.8 °C
Explanation:
Given that
m= 2 kg
T₁=200 °C
time ,t= 10 min = 600 s
Work input = 1 KW
Work input = 1 x 600 KJ=600 KJ
Heat input = 0.5 KW
Q= 05 x 600 = 300 KJ
Gas is ideal gas.
We know that for ideal gas internal energy change given as
ΔU= m Cv ΔT
For air Cv= 0.71 KJ/kgK
From first law of thermodynamics
Q = ΔU +W
Heat input taken as positive and work in put taken as negative.
300 KJ = - 600 KJ + ΔU
ΔU = 900 KJ
ΔU= m Cv ΔT
900 KJ = 2 x 0.71 x (T- 200 )
T=833.8 °C
So the final temperature is T=833.8 °C
Answer:
Access to energy underpins human comfort, mobility, economic prosperity and social progress. It touches nearly every aspect of modern life. Over the course of its long history of more than a century, ExxonMobil has evolved from a regional marketer of kerosene to an advanced energy and chemical innovator, and one of the largest publicly traded companies in the world. An industry leader in almost every aspect of the energy and chemical manufacturing businesses, we operate facilities or market products in most of the world’s countries, explore for oil and natural gas on six continents, and research and develop next-generation technologies to help meet the dual challenge of fueling global economies while addressing the risks of climate change.
