Heat - Energy Transfer Question

AI Thread Summary
To solve the homework problem regarding the water heater's energy transfer, the relevant formula is Q = mcΔT, where Q is the heat energy, m is the mass of water, c is the specific heat capacity of water, and ΔT is the temperature change. Given that the water heater generates 32,000 kJ/h, this translates to 32,000,000 J, and the temperature change is 35 degrees Celsius. The specific heat capacity of water is approximately 4,186 J/kg°C. By rearranging the formula to find mass (m = Q / (cΔT)), the mass of water that can be heated can be calculated. Understanding these components will allow for the correct application of the formula to find the solution.

Hi, one of my homework problems i received was "A water heater can generate 32, 000kJ/h. How much water can it heat from 15 C to 50 C per hour?" I am having trouble figuring out what formula I would use?
 
Physics news on Phys.org
Let's see, you have the amount of heat, Q=32,000,000 J
you have a change in temperature, \Delta T=35 degrees
you have water with a specific heat, c = (look it up)
and you need mass m=?

You can't find the right formula? You should look again.
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
