Answer: c. increase in surface tension
Explanation:
a) Viscosity : is defined as the resistance to the flow of a fluid. More are the inter molecular forces between the particles of a liquid, the more the viscosity of the liquid and thus it will flow slowly.
Viscosity decreases with increase in temperature as the forces among particles decrease due to increase in kinetic energy and thus they offer less resistance to flow.
c) Surface tension : is the downward force acting on the surface of liquid due to presence of inter molecular forces or cohesive forces between the particles of liquid.
Surface tension decreases with increase in temperature as the forces among particles decrease due to increase in kinetic energy.
d) Vapor pressure: Vapor pressure of a liquid is defined as the pressure exerted by the vapors in equilibrium with the solution at a particular temperature.
Vapor pressure increases with increase in temperature as the forces among particles decrease ad more particles can escape as vapors.
e) Evaporation is the the process in which liquid changes into gaseous state below its boiling point.
Evaporation increases with increase in temperature as the forces among particles decrease ad more particles can escape as vapors.
Answer:
48546.7kg or 48546745g
Explanation:
so from this u can work out the amount of moles in phosphorous by doing mass / mr you have to convert the mass in kg to g so you times it by 1000. then divide it by 31 which is the mr of phosphorous. then u can use the molar ratio which is 2:1 . Then use the equation mass= moles*mr
so 97000*1000/31=312903moles
2:1
so 312903/2=156451 moles of ca3(PO4)2
so mass= moles*mr
156451*310.3=48494g
hope this helps u to understand(*°▽°*)
A because product needs to equal reactants
The yeast and Hydrogen Peroxide is the chemical change, because when something is changed chemically, there is a chemical added that cannot be taken away to make it go back to it's original state. However when you're blowing bubbles in milk, no chemicals were added and it will go back to it's original state.
