If the specific heat of a material is 0.416 J/(g°C) and sample absorbs 50 J when it is heated from 30°C to 50°C what is the mass
ololo11 [35]

The mass of the sample of the material is 0.1664 g.

<h3 /><h3>What is specific heat?</h3>

The amount of energy needed to raise the temperature of one gram of a substance by one degree Celsius.

By the formula of specific heat

Q = mc \Delta T

Given, that the specific heat (c) of material is 0.416 J/gC

The difference in temperatures is 30°C to 50°C

The mass=?

Q = heat, 50 J

Putting the values in the equation

\rm 50\;J = m \times 0.416 J/g^\circ C \times (50 - 30)\\\\m = \dfrac{0.416 J/g^\circ C \times 20}{50} = 0.1664 g

Thus, the mass of the samples is 0.166 g.

A sample of gold has a mass of 96.5 g and a volume of 5.00 cm3. What is the density of gold in g/cm3
viva [34]

Answer: The density would be p = 19.3 g/cm3 because

Explanation:  because if you calculate density the formula would be d = <u>m</u>

                                                                                                                             v

so just use the values giving and you get the answer  by plugging the 96.5 mass then 5 for the volume then divide it.

Occurs in plant life : Both

a way to store energy : Both

Catabolic Reaction : Cellular Respiration

a way to release energy : Both

involves oxygen and carbon dioxide : oxygen releases by the process of photosynthesis. Oxygen is involved in areobic respiration and not in anarobic respiration.
