Question 25 I point
5.0g of water at 25°C is dropped onto a large block of ice at 0°C. The water cools to 0°C and
some of the ice melts.
Assume that all the energy lost by the water is gained by the ice.
What is the mass of ice that melts?
The specific heat capacity of water is 4.2J/(g°C).
The specific latent heat of fusion of ice is 340J/g.
A 0.0629
B 0.0879
C 1.59
D 10g

Imagine that you have two balloons (or, better yet, actually inflate two balloons, if possible). create static electricity around one of the balloons by rubbing it against your hair or your sweater and then bring that balloon close to the other balloon, which has not been charged. try this with at least one other object—and for variety in the discussion, avoid using an object already described by your classmates. then, for your initial post to the discussion, answer the following questions: what happened with the two balloons?
