Which substance will require more energy to heat if all the samples have the same mass? A chart with two columns and nine rows.

The first column's header is Substance. The second column's header is Specific Heat J divided by (g times degrees Celsius) First row: Substance—Lead; Specific Heat—0.129. Second Row: Substance—Tin; Specific Heat—0.21. Third row: Substance—Silver; Specific Heat—0.235. Fourth row: Substance—Iron; Specific Heat—0.449. Fifth row: Substance—Calcium; Specific Heat—0.647. Sixth row: Substance—Granite; Specific Heat—0.803. Seventh row: Substance—Aluminum; Specific Heat—0.897. Eighth row: Substance—Magnesium; Specific Heat—1.023. Lead Magnesium Iron Aluminum

Here we have to identify the sample which need more energy to heat the sample 1 degree Celsius.

Among the given elements magnesium will require more energy than the others to heat.

As per the definition of specific heat of a compound, the amount of heat required to increase the temperature of the material 1 degree Celsius is the specific heat of the material.

The given data are-

substance              specific heat

Lead                            0.129

Tin                                0.21

Silver                            0.235

Iron                              0.449

Calcium                        0.647

Granite                         0.803

Aluminium                   0.897

Magnesium                  1.023

From the given data lead, magnesium, iron and aluminium have the specific heat 0.129, 1.023, 0.449 and 0.897 respectively. Thus magnesium will require more energy than the others to heat.

-BARSIC- [3]

Answer:

0.02 m

Explanation:

∆U = q + w

w = ∆U - q = (1380 - 2040) J = -660 J

w = -p∆V = -pA∆h

∆h = -w/(pA)

p = 1 bar × (100000 Pa/1 bar) = 100000 Pa

∆h = -(-660 J)/(100000 Pa×0.33 m²) = 0.02 m

Calculate the number of repetitions of the β-oxidation pathway required to fully convert a 18-carbon activated fatty acid to ace
Anna35 [415]
The number of repetition of the Beta oxidation requires to fully convert 18 carbon activated fatty acid to Acetyl COA molecule is NINE.
Beta oxidation of fatty acid involves oxidative removal of successive two carbon units in the form of acetlyl COA, starting from the carboxyl end of the fatty acyl chain. Thus, a fatty acid which has 18 carbons will have to undergo nine repetition of beta oxidation before it is reduced to an acetyl COA.

Iteru [2.4K]
This is a homogenous mixture because you cannot differentiate between the members of the mixture. A technique might be heating them until one melts and evaporates due to different boiling temperatures, or mixing them together with fluids that would dissolve one, yet keep the other one whole.
