Answer:
232 J/K
Explanation:
The amount of heat gained by the air = the amount of heat lost by the tea.
q_air = -q_tea
q = -mCΔT
q = -(0.250 kg) (4184 J/kg/ºC) (20.0ºC − 85.0ºC)
q = 68,000 J
The change in entropy is:
dS = dQ/T
Since the room temperature is constant (isothermal):
ΔS = ΔQ/T
Plug in values (remember to use absolute temperature):
ΔS = (68,000 J) / (293 K)
ΔS = 232 J/K
Plate tectonics and the earth is separated into many pieces which move around and create earthquakes and volcanoes
<span>The candy before has undergone physical change after manipulation because it says that it will make the cotton candy denser. Making it denser probably doesn't have to change any chemical components of the candy.</span>
Since the density of water is 1g/cm^3, The mass of water needed to fill the tank is 150000 grams
