Answer:
0.3936 J/gC
Explanation:
using the formula: q=mcΔt
q= 7032J
m=812g
ΔT = 22C
plug in and solve:
7032=(812)(c)(22)
c=7032/(812)(22)
c=0.39 J/gC
Answer:
302.75 Liters
Explanation:
Given:
P = 1 atm
V = ?
n = 13.5 moles
R = 0.0821 atm x L / mole x K
T = 273.15 K
PV = nRT
(1) (V) = (13.5) (0.0821) (273.15)
V = 302.75 Liters
The form of heat transfer taking place in the crust of the Earth would be Convection.
Answer:
The answer is B. Atomic Mass
Answer:
Region B, because the pressure inside the cylinder is equal to the vapor pressure of water at 80∘C when both liquid and gas phases are present.
Explanation:
As expansion occurs, liquid water evaporates reversibly, holding the pressure constant at the equilibrium vapor pressure of water at 80∘C(0.47atm) 80∘C (0.47 atm). When all of the liquid has evaporated, the pressure drops and follows the ideal gas law.
