The sun is beating down on the concrete. it's a hot day, and you're in the house where it's conditioned. Your feet are fairly cool. When you step outside on the concrete the coldness in your feet seep into the concrete, and the heat from the concrete takes the cold away. It's like when a pot is on the stove, the pan transfers all it's cold to the hot, and the fire replaces the cold. Hope this helps!
Answer:
1.67 atm.
Explanation:
- We can use the general law of ideal gas: PV = nRT.
where, P is the pressure of the gas in atm (P = ??? atm).
V is the volume of the gas in L (V = 5.0 L).
n is the no. of moles of the gas in mol (n = 0.5 mol).
R is the general gas constant (R = 0.0821 L.atm/mol.K),
T is the temperature of the gas in K (T = 203 K).
∴ P = nRT/V = (0.5 mol)(0.0821 L.atm/mol.K)(203 K)/(5.0 L) = 1.67 atm.
Answer:
theory
Explanation:
A theory has been tested and proven several times and oftentimes has a large amount of information, research, and evidence standing behind it.
Hope this helps! :)
The third option is the answer
Weathering is the process that changes solid rock into sediments. Sediments were described in the Rocks chapter. With weathering, rock is disintegrated. It breaks into pieces.
1 Cal ---------- 4.184 J
? Cal ---------- 130.0 J
130.0 x 1 / 4.184 => 31.07 Cal
hope this helps!
