Based on the definition of specific heat and the information provide below, if the same amount of heat is added to 1 kg of all t
REY [17]
It would be the one with the highest Specific Heat constant

The equation for specific heat is:

Q=mCT

If we rearrange for T, we get:

T=Q/mC

Since m is just 1 Kg, we can ignore it and say that:

T=Q/C

Let’s just give an arbitrary number to C and solve for each individual species

Q=1 J

Helium - 1J/5193 = .00019257

Steel - 1J/490 = .00204082

Aluminum - 1J/897 =.00111483

Water - 1J/4182 = .00023912

This proves that Steel, with the lowest Specific Heat will increase the most.

What was the major weakness of Wegener's theory of continental drift
Alik [6]

Alfred Wegener proposed the continental drift theory  in four reasons. One, he hypothesized that the continents were once a giant continent. Two, he observed that there are fossils found of the same kind in the different locations. Three, he found that the edge of opposing continents somehow fits if they are combined, almost like a puzzle. And four, there are glacial scars that are left behind by a larger glacial continent. His greatest weakness of Alfred Wegeners’ continental drift theory was he could not explain what kind of force that caused this continents to move far from each other.
