Although the moon's distance from earth varies each month because of its eccentric orbit, the moon's mean distance from Earth is nonetheless increasing at the rate of about 3.8 centimeters (1.5 inches) per year
It depends on the process.
Like for example if the process is isothermal(temperature is constant), you can use,
PV = constant or P1V1 = P2V2 where P1V1 are initial conditions and P2V2 are final.
For adiabatic process,
PV^gamma = constant or P1V1 ^gamma = P2V2 ^gamma.
where gamma = Cp
------
Cv
Cp = specific heat at constant pressure and Cv = specific at constant volume.
Value of Gamma will be given in question.
Hope this helps!
Answer:
Soap decreases surface tension by changing the way water behaves on the surface. Hard and soft water react differently when soap is added to them.
Explanation: i think it is this
We shall consider V, the volume and T, the temperature.
According to Boyle's Laws:
In our case:
Answer:
677.39 g/mol
Explanation:
Step 1: Find molar masses of elements
Carbon (C) - 12.01 g/mol
Hydrogen (H) - 1.01 g/mol
Oxygen (O) - 16.00 g/mol
Step 2: Multiply the amount present
12.01 g/mol · 46 = 552.46 g/mol
1.01 g/mol · 92 = 92.92 g/mol
16.00 g/mol · 2 = 32.00 g/mol
Step 3: Add up all the molar masses to find compound molar mass
552.46 g/mol + 92.92 g/mol + 32.00 g/mol = 677.39 g/mol
