Because heat keeps us warm and water hydrates the planet i guess?????

Substance A would have a delta T (change in temp) rise 1/2 the rise in substance B.
Q=mc x delta T
Q= heat energy in Joules
m= mass of substance heated or cooled
c= specific heat
ΔT is change in temp.
Solve for change in temp=. Q/mc
Specific heat and mass are not inversely proportional to heat energy input.
Putting into real world scenario of using water to heat a building.
Specific heat of water is 1.
It takes 1 btu to raise one pound of water 1 degF. at a base of 60 degF
Acetone specific heat is .51
So it takes half the amount of heat input to get a 100 degree ΔT, as compared to water.

Answer:
8 m/s² south
Explanation:
Given:
v₀ = 40 m/s
v = 0 m/s
Δx = 100 m
Find: a
v² = v₀² + 2a (x − x₀)
0² = 40² + 2a (100)
a = -8
The acceleration is 8 m/s² south.
The answer is "Density". defined as amount of matter per unit volume. It is also a measurement of how tightly matter is crammed together. Density is mass per unit volume. written as ρ = m/v. Greek letter ρ (rho). The derive unit for density is usually in Kg/m³.
