Write a hypothesis for Part II of the lab, which is about the type of material an object is made of, and its ability to absorb o

r release thermal energy. Use the format of "if . . . then . . . because . . .” and be sure to answer this part of the lesson question: "How does the type of material affect thermal energy transfer?”

Answer:

Different materials will change temperature at different rates when exposed to the same amount of thermal energy. This is because each substance has its own specific heat.

Explanation:

that is the answer

Answer:

A hypothesis I would write for the second part of the lab

Explanation:

If different materials with a same volume are exposed to a same amount of  thermal energy, then they will transfer different amounts, since each material has a unique specific heat.

Nostrana [21]

The question is incomplete, the complete question is;

The normal boiling point of acetic acid is 118.1°C. If a sample of the acetic acid is at 125.2°C, predict the signs of ∆H, ∆S, and ∆G for the boiling process at this temperature.

A. ∆H > 0, ∆S > 0, ∆G < 0

B. ∆H > 0, ∆S > 0, ∆G > 0

C. ∆H > 0, ∆S < 0, ∆G < 0

D. ∆H < 0, ∆S > 0, ∆G > 0

E. ∆H < 0, ∆S < 0, ∆G > 0

Answer:

A. ∆H > 0, ∆S > 0, ∆G < 0

Explanation:

During boiling, a liquid is converted to vapour. This is a phase change for which heat is absorbed because energy must be taken in to break the intermolecular bonds in the liquid before it can be converted to a gas. Hence ∆H>0

Secondly, a phase change from liquid to gas leads to an increase in entropy hence ∆S>0.

Thirdly, the process is spontaneous. For every spontaneous process ∆G<0

Can two atoms with the same mass number ever be isotopes of each other ?
Marianna [84]
NO, two atom with the same mass number can never be isotope of each other.
This is because for atoms to be considered as isotopes, they must have the same number of protons but different number of neutrons. There is no way two atoms will have the same mass number and their proton number will be the same, this means that two atoms with the same number of mass number can not be isotope of each other.

The density of ice is 0.917 g/cm3. How much volume does 52.3 g of ice occupy? Show your work.
mash [69]

Answer:

The answer is

<h2>57.0 mL</h2>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

volume =  \frac{mass}{density}

From the question

mass of ice = 52.3 g

density = 0.917 g/cm³

The volume is

volume =  \frac{52.3}{0.917}  \\  = 57.0338058

We have the final answer as

<h3>57.0 mL</h3>

Hope this helps you
