A 6-g ice cube at −8°C is dropped into 70 g of water at 31°C. (a) After enough time has passed to allow the ice cube and water to come into equilibrium, what is the temperature of the water? (b) If a second ice cube is added, what will the temperature

2. ## Physics

Three identical blocks, A, B, and C, are on a horizontal frictionless table. The blocks are connected by strings of negligible mass, with block B between the other two blocks. If block C is pulled horizontally by a force of magnitude F = 28 N, find the

3. ## Physics

Suppose the slope of a beach underneath the ocean is 20 cm of dropoff for every 1.6 m of horizontal distance. A wave is moving inland, slowing down as it enters shallower water. What is its acceleration when it is 12 m from the shoreline? (Let the +x

4. ## PHysics

What is the total energy of a 15-kg mass attached to a spring oscillating horizontally with an amplitude of 20 cm and an angular frequency of 32 rad/s?

5. ## Physics

A 0.51-kg mass is attached to a horizontal spring with k = 108 N/m. The mass slides across a frictionless surface. The spring is stretched 26 cm from equilibrium, and then the mass is released from rest. (a) Find the mechanical energy of the system. (b)

6. ## physics

A crate of oranges slides down an inclined plane without friction. If it is released from rest and reaches a speed of 4.476 m/s after sliding a distance of 2.33 m, what is the angle of inclination of the plane with respect to the horizontal?

7. ## mathematical literacy

Are there available degrees relating to comerce, that can be done with Maths Lit, and not Maths. Preferably at a good institute like uct, uj, ukzn, etc.

8. ## Chemistry

What does "Kc" mean?

1. ## Chemistry

Supposing all the "gas" is water vapor. The source below gives the specific heat of water vapor and liquid water: (2.000 J/(g·°C) x ((0.07796 g) x (125 ºC - 100 ºC) = 3.898 J from cooling the vapor to 100 ºC (0.07796 g H2O) / (18.01532 g H2O/mol) =

I'm not too sure how to add the latent heat part in there, but I'll reread that section in my book and see if I can figure something out.

The answers are 21.9 degree c and 14.2 degree c. I've tired figuring out a way to use the dE = Q - W equation to solve this problem, but it hasn't been working.
