The correct answer D: all of the above
Answer:
d. 149 ⁰C.
Explanation:
Given;
mass of the block of ice, m = 2 kg
specific heat capacity of the ice, C = 2090 J/(kgK)
initial temperature of the ice, t₁ = -90 ⁰C
heat added to the ice, H = 1,000,000 J
let the final temperature of the ice = t₂
The final temperature of the ice after adding the heat is calculated as follows;

Therefore, the new temperature of the water is 149 ⁰C.
I'm pretty sure the answer is B: <span>establish public doubt

Answer:as a coloring (pigment) in makeup or paint
Explanation:
Visibly you can see that the two copper are different sizes so the mass and volume are different. No information is given about the temperature but they are side by side so you can assume they're both room temp. The density is a ratio of mass per volume. The density will remain the same unless the two are different purities or physical states.
