Specific heat capacity and latent heat.

AI Thread Summary
To determine the temperature rise of 2 kg of water when a 210 heater is switched on for 200 seconds, one must first look up the specific heat capacity of water, which is crucial for calculations. The specific heat capacity indicates how much energy is required to raise the temperature of a unit mass of water by one degree Celsius. By combining the specific heat capacity with the power of the heater and the time it operates, the temperature change can be calculated using the appropriate formula. Understanding the units involved is essential to ensure the calculations yield the correct temperature rise. This approach will lead to a clear solution for the problem presented.

a 210 heater is places in 2 kg of water. What temperature rise is produced if the heater is switched on for 200 seconds?

I need your help please.

You need to look up the specific heat capacity of water. Think about the units of specific heat capacity and the units of the quantities in the question. How can these all be combined to give you an answer in the correct units?
 
^ I have no idea about that i posted this for an answer with good explanation please
 
Well, it's easy to look up the specific heat capacity for water... just type it into Google or something. Then you need to think about how to use this information - again, the units will be a big hint and will tell you what the specific heat capacity represents.
 
Also try looking for the relevant equation. That should help you along the way to determining the answer.
 

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'

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...
