Use the concept of specific heat to analyze the following observation.

two pieces of metal with exactly the same mass are placed on a surface in bright sunlight. the temperature of the 1st block increases by 3°c while the temperature of the 2nd increases by 8°c. if the specific heat of the 2nd block is 0.24 j/g-k, what is the specific heat of the 1st block?
a) 0.3 j/g-k
b) 0.64 j/g-k
c) 1.2 j/g-k
d) 1.56 j/g-k

i need this !

0.64 J/g-K

First, if we consider the formula q=mCΔT for each block, the "q" for both are equal. Therefore,

m1C1ΔT1 = m2C2ΔT2

Since the masses are the same, cancel them. Leaving

C1ΔT1 = C2ΔT2

Plug in the known values for C and &DeltaT. Solve for C1. This will result in 0.64 J/g-K.

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.

7*5*36= 1260 it's all about multiplying

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
