A 20.0 g sample of copper at 25.0 °c absorbs 475 j. What is the final temperature of the copper? (specific heat capacity of copp er is 0.385 j/g °c.)
1 answer:
Given data:
Mass of copper (m) = 20.0 g
Initial temperature of Copper (T1)= 25 C
Final temperature = T2
Heat absorbed by copper (Q) = 475 J
Specific heat of Copper (c) = 0.385 J/g C
Formula:
Q = mcΔT
= mc(T2-T1)
475 = 20*0.385*(T2-25)
62.08 = T2-25
T2 = 87.08 = 87.1 C

Mixtures are a substance made of combining two or more different kinds of matter :)
Hope this helped!
The answer is d I think. Don’t quote me if I’m wrong
i would have to say boiling because all that does is make the molecules do that fancy word for moving to the surface when they heat.
The answer is b because the autor in the passage said .
I feel the exact same way and what I would do is just try talking to them ,it may seem hard at first but try to start a conversation and maybe ask their friends about them or if they still like you
