I think the answer is the number of protons.
Answer:
The answer to your question is 510.7 kJ
Explanation:
Data
Q = ?
Volume = 2 L
Temperature 1 = T1 = 19°C
Temperature 2 = T2 = 80°C
Specific heat = 4.186 J/kg°C
Density of water = 1 g/ml
Equation
Q = mC(T2 - T1)
Process
1.- Calculate the mass of water
mass = density x volume
mass = 1 x 2000
mass = 2000 g
2.- Substitute values in the Heat formula
Q = (2000)(4.186)(80 - 19)
-Simplification
Q = (2000)(4.186)(61)
-Result
Q = 510692 J or 510.7 kJ
the definition of y'all is "you all"

Green plants absorb some of the sunlights energy
Answer:
V₂ = 1223.2 mL
Explanation:
Given data:
Pressure of gas = 820.4 mmHg
Initial volume of gas = 900.0 mL
Initial temperature = 25.0°C (25+273=298K)
Final temperature = 132.0°C (132.0 +273 = 405 K)
Final volume = ?
Solution:
Solution:
The given problem will be solve through the Charles Law.
According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.
Mathematical expression:
V₁/T₁ = V₂/T₂
V₁ = Initial volume
T₁ = Initial temperature
V₂ = Final volume
T₂ = Final temperature
Now we will put the values in formula.
V₁/T₁ = V₂/T₂
V₂ = V₁T₂/T₁
V₂ = 900.0 mL × 405 K / 298 k
V₂ = 364500 mL.K / 298 K
V₂ = 1223.2 mL
