Answer:
a) A satellite is warmed by sunlight.
Explanation:
Heat transfer by radiation mostly involves heat gain or heat loss from the Sun. In this case, Option A is the only option where sunlight is involved so it is the best example of heat transfer by radiation.
Explanation:
Generally, heat flows from a hot environment to a cold (lesser temperature) environment. In this case, the soup is the hot environment and the air is the cold temperature.
Heat would continue to flow from one environment to another until thermal equilibrium is reached. At this thermal equilibrium, both environments would have the same temperature.
Answer:
wave length=speed/frequency
=345/229
Moles = mass/molar mass, so n(C2H6O)= 16.0 / (12+12+(1x6)+16)
=0.348 (to correct sig figs)
Answer:
The answer to your question is V2 = 1.3 l
Explanation:
Data
Pressure 1 = P1 = 1.5 atm
Volume 1 = V1 = 2.50 l
Temperature 1 = T1 = 22°C
Pressure 2 = P2 = 3 atm
Volume 2 = V2 = ?
Temperature 2 = T2 = 35°C
Process
1.- Convert temperature to °K
T1 = 22 + 273 = 295°K
T2 = 35 + 273 = 308°K
2.- Use the combine gas law to solve this problem
P1V1/T1 = P2V2/T2
-Solve for V2
V2 = P1V1T2 / T1P2
3.- Substitution
V2 = (1.5 x 2.5 x 308) / (295 x 3)
4.- Simplification
V2 = 1155 / 885
5.- Result
V2 = 1.3 l
