The statement "<span>For water to become a mechanical weathering agent through ice wedging, it needs to go through a cycle of freezing and thawing." is true</span>
Answer: A. 
Explanation:
The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.
Q = Heat absorbed = 4.56 J
m = mass of substance = 123 g
c = specific heat capacity = ?
Change in temperature ,
Putting in the values, we get:
The specific heat of a 123 g substance that requires 4.56 J of heat in order to increase its temperature by 12.32 °C is
Atomic particles Because the usually have a chain reaction when blown up
It has a higher boiling point and a lower freezing point
<span>1) osmotic pressure exerted by a solution is equal to the molarity multiplied by the absolute temperature and the gas constant r.
Call: P = osmotic pressure; C = molarity; T = absolute temperature
=> P = C * T * r
2) </span><span>write an equation that will let you
calculate the molarity c of this solution. your equation should contain
only symbols. be sure you define each symbol other than r.
</span><span>
</span>=> C = P / (rT)
Answer: C = P / (rT)
