AI Thread Summary
To calculate the molar specific heat (Cp) using the equation Q=m*Cp*(change in temperature), first determine the heat capacity per mass. Then, convert this value to heat capacity per mole by multiplying it by the molar mass of the substance. Alternatively, you can calculate the number of moles from the given mass and use that to solve for Cp directly. Both methods will yield the molar specific heat needed for the problem. Understanding these conversions is crucial for accurate calculations in thermodynamics.

Homework Statement



From Q=m*Cp*(change in temperature), they give me all but Cp, which I calculate, and they also give me a mass per mole of the substance. Now the next part of the problem asks for the molar specific heat of the substance, but the equation for this eludes me.

So you've calculated the heat capacity per mass? Convert your heat capacity per mass into heat capacity per mol. Look at the units to see. You will just multiply your answer by the molar mass.

Or, do the calculation again, this time convert the mass given into moles

#moles = (mass in grams) / (molar mass in grams per mole)

and solve for Cp.

Either way.
 
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
Thread 'Variable mass system : water sprayed into a moving container'
Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
