AI Thread Summary
To calculate the mass of a block of ice using thermal dynamics, it's essential to understand that 333,465 Joules of energy is required to melt 1 kg of ice at 0 degrees Celsius. The density of ice is approximately 917 kg/m^3, which can help determine the mass of a cubic foot of ice. By applying the specific heat formula, the mass can be calculated as M = 333,465 joules divided by the product of 2000 joules/kg-C and the temperature change (20 degrees Celsius), resulting in a mass of about 8.336 kg. This calculation demonstrates the relationship between energy, mass, and temperature in thermal dynamics. Understanding these principles is crucial for accurately determining the mass of ice in thermal calculations.

Ok, I don't quite understand the concept of thermal dynamics. So, I need some help here.

When ice melts it takes 333,465 Joules of energy to convert one 1KG of solid ice into liquid water at 0 degrees celsius. Suppose that you have a one cubic foot block of ice.

I need to find the MASS. Can someone please point me in the right direction? :biggrin:

Here's what i got so far:

333,465j=M*2000j/kg-celsius(0-20)?

I presume the question is to find out how much energy is needed to melt that much ice at 0 degrees? If so, look up the density of ice in order to find the mass of this block. (I think it's something like 917 kg/m^3.)
 


Sure, I'd be happy to help with some thermal dynamics! First, let's break down the information given. Thermal dynamics is the study of how heat and energy transfer and transform in a system. In this case, we are looking at the specific heat of ice, which is the amount of energy needed to raise the temperature of one kilogram of ice by one degree Celsius. This value is 2000 joules per kilogram per degree Celsius.

Now, let's apply this information to the given scenario. We know that 333,465 joules of energy is needed to melt one kilogram of ice at 0 degrees Celsius. So, we can set up an equation:

333,465 joules = M (mass of ice) x 2000 joules/kg-C x (0-20 degrees Celsius)

Solving for M, we get:

M = 333,465 joules / (2000 joules/kg-C x 20 degrees Celsius) = 8.336 kg

Therefore, the mass of the ice cube is approximately 8.336 kilograms.

I hope this helps! Let me know if you have any other questions or need further clarification. Keep up the good work!
 
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 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
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...
