Answer:
The correct answer is Sugar has a greater solubility than sand.
Sugar will easily dissolve in water because it has a lower density than sand, therefore it has a greater solubility.
Answer:
Net force= -5N+5N =0
Therefore there is no change in motion
Explanation:
Phase transition is when a substance changes from a solid, liquid, or gas state to a different state. Every element and substance can transition from one phase to another at a specific combination of temperature and pressure.
382.75 is the temperature of the 0.750 mol of an ideal gas occupy a volume of 35.9 L at 114 kPa.
Explanation:
Given:
number of moles (n) = 0.750
volume of the gas = 35.9 litres
pressure on the ideal gas = 114 kPa or 1.125 atm
R (gas constant) = 0.0821J/Kmole
Absolute temperature of gas in celcius =?
the equation for the ideal gas is
PV = nRT
putting the values in the above equation:
T = ![\frac{PV}{RT}](https://tex.z-dn.net/?f=%5Cfrac%7BPV%7D%7BRT%7D)
= ![\frac{1.125 X 35.9}{0.75 X 0.0821}](https://tex.z-dn.net/?f=%5Cfrac%7B1.125%20X%2035.9%7D%7B0.75%20X%200.0821%7D)
= 655.907
655.9 kelvin is the temperature of the ideal gas.
To convert this unit of kelvin into degree celcius:
K-273.15 = C
655.9 - 273.15
= 382.75 degrees
382.75 degrees celcius is the temperature of the ideal gas.
