True or false When heat flows to an object, it can change states.

Chemistry
1 answer:
emmasim [6.3K]3 years ago
7 0

Answer: True

Explanation:

The matter exists as solid, liquid or gas. These are called the states of matter. The change of matter from one state to another can be achieved by heating or cooling.

The solid state can be converted into liquid state by providing heat to solid. The heat will make the particles move farther, resulting into liquid state.

Similarly when liquid state is provided heat, it changes to gaseous state. The heat will make the particles move much more faster.

Thus the statement that when heat flows to an object, it can change states is True.

How many grams of CO2 are produced when 80.0g of O2 react with 13.2 of C3H8 according to the following equation ? C3H8 + 5O2 → 3
iren [92.7K]
For each C3H8, you get 3 C's in CO2, so 13.2 x 3 = 39.6
For each O2, you use 5 to make 3 O2s, so (80/5)3 = 48
39.6+48= 87.6 grams

Parts of respiratory system:

Nose and Nasal Cavity, mouth, Pharynx, Larynx, Trachea, Bronchi and Bronchioles, Lungs and Muscles of Respiration.

Respiratory system function:

Your respiratory system is the network of organs and tissues that help you breathe. This system helps your body absorb oxygen from the air so your organs can work. It also cleans waste gases, such as carbon dioxide, from your blood.

Alveoli:

Alveoli are tiny sacs of air in your lungs that take up the oxygen you breathe and keep it going. The alveoli ventilate, diffuse and peruse in your lungs.

What is the density of object C? Does it sink or float in water?
nirvana33 [79]

Answer:

0.96 g/cm3, and it will float!

Explanation:

I've explained how to do this before (remember me? lol), but ig I'll do it again..

By looking at the graph you can see that Object C has a mass of ~24 grams and a volume of ~25 cm3

Density = Mass/Volume -> 24 grams/25 cm3 = 0.96 g/cm3

Density of water is 1 g/cm3

Object C is less dense than water and therefore will float (just barely, though)

Which one of the following characteristics indicates the presence of weak intermolecular forces in a liquid?A) none of the above
grin007 [14]

Answer:

C) a low heat of vaporization.

Explanation:

It is C) a low heat of vaporization.

Low heat of vaporization means less amount of energy is required to vaporize a liquid. This further means the liquid has weaker intermolecular force of attraction that is why on provide lesser heat only it vaporizes.

Low vapor pressure, high boiling point and high critical temp. all contribute to strong intermolecular forces in a liquid
