Answer:
The temperature of the system once the equilibrium has been reached = 372.55K
Explanation:
Heat capacity of gold = 129 J/Kg*c.
Heat capacity of water
4,184 J/Kg*c.
Mass of gold = 75g = 0.075Kg
Mass of water = 200g = 0.2Kg
From conservation of energy
m1×C1×(t11 - t2) = m2×C2×(t2- t21)
Substituting we have
0.075 × 129×(1000-t2) = 0.2× 4184×( t2 -300) =solving for t2, we have
933.55×t2 = 347790
or t2 = 372.55K
The temperature of the system once the equilibrium has been reached = 372.55K
The answer is: 175 grams of fat are in the round.
m(ground round) = 1.33 ib.
First convert ib (pounds) to g (grams):
1 pound (lb) is equal to 453.592 grams (g).
m(ground round) = 1.33 ib · 453.592 g/ib.
m(ground round) = 603.28 g.
ω(fat) = 29% ÷ 100%.
ω(fat) = 0.29; mass percentage of fat.
m(fat) = ω(fat) · m(ground round).
m(fat) = 0.29 · 603.28 g.
m(fat) = 175 g; mass of fat.
Answer:
d) gases that absorb infrared radiation
water vapor, carbon dioxide, methane, and other trace gasses in the Earth's atmosphere absorb the longer wavelengths of outgoing infrared radiation from the Earth's surface.
