Answer:
The ratio of the momentum imparted to gun #1 to that imparted to gun #2 is equal to 2 : 1
Explanation:
Detailed explanation and calculation is shown in the image below
Answer:
Explanation:
According to given:
- molecular mass of glycerin,
- molecular mass of water,
- ∵Density of water is
- ∴mass of water in 316 mL,
- mass of glycerin,
- pressure of mixture,
- temperature of mixture,
<em>Upon the formation of solution the vapour pressure will be reduced since we have one component of solution as non-volatile.</em>
<u>moles of water in the given quantity:</u>
<u>moles of glycerin in the given quantity:</u>
<u>Now the mole fraction of water:</u>
<em>Since glycerin is non-volatile in nature so the vapor pressure of the resulting solution will be due to water only.</em>
Answer: D
Explanation: The chemical bonds in the food store energy that is released when we eat it.
Answer:
Explanation:
Here by ideal gas equation we can say
now we know that pressure is kept constant here
so we will have
since we know that number of moles and pressure is constant here
so we have
now we know that initial temperature is 17.8 degree C
and finally volume is doubled
So we have
so final temperature will be
