Answer:
46.73ºC
Explanation:
The sheets will change heat to achieve the thermal equilibrium, it means that they'll have the same final temperature (T). The heat (q) must be equal for both in magnitude, but with opposite directions.
The heat flows from the higher temperature for the lower, so it flows from the iron (Fe) to the gold (Au) sheet:
qAu = -qFe
The heat can be calculated by the equation:
q = m*cp*ΔT
Where m is the mass, cp is the specif heat capacity, and ΔT the temperature variation.
CpAu = 0.129 J/gºC
CpFe = 0.444 J/gºC
10.2*0.129*(T - 19.4) = -19.9*0.444*(T - 50.8)
1.3158*(T - 19.4) = -8.8356*(T - 50.8)
1.3158T - 25.52652 = -8.8356T + 448.84848
1.3158T + 8.8356T = 448.84848 + 25.52652
10.1514T = 474.375
T = 46.73ºC
Answer:
1. 380 parts per million (0.038%)
Explanation:
By volume, dry air, which makes up the earth's atmosphere is roughly made up of 78.09 % nitrogen gas, 20.95 % oxygen gas, 0.93% argon gas, 0.04% carbon dioxide gas, and trace amounts of other gases. So the answer to this question is the one that is closest to 0.04 %, 1.
Answer:
undergo global warming at a faster rate than what we are seeing currently
Explanation:
because sun and volcanoes are the hottest things so it would undergo global warming at a faster rate.
