Explanation:
If water is ice-form, only the gap between molecules reduces but the molecule remains the same. The gap between liquid water molecules is greater than that between the molecules. That's why ice is thinner than water.
The intermolecular gap now increases in the gaseous form, which makes it less heavier than solid ice and liquid water. However, the molecule still remain the same.
Answer:
The correct answer is B).
Explanation:
The factors that accelerate a chemical reaction are:
- Temperature: at a higher temperature, the speed of a reaction is increased.
- Pressure: the higher this is, the greater the collisions between molecules and an acceleration of the reaction speed will occur.
-Catalysts: correspond to substances that accelerate chemical reactions, an example are enzymes. There are catalysts that increase the reaction rate and others that generate the opposite effect (they are inhibitors).
There are also other factors that accelerate a chemical reaction such as the concentration of reagents.
Answer:
THE PRESSURE OF THE TIRE ON THE TRIP HOME AT THE ROAD SURFACE TEMPERATURE OF 32°C IS 160 kPa.
Explanation:
Initial Pressure = 75 kPa
Initial temperature = 15 °C
Final temperature = 32 °C
Final pressure = unknown
Using the combined equation of gases;
P1V1/T1 = P2V2/ T2
Since the tire will have the same volume of air in it showing that volume of constant both at the repair shop and on the road surface.
The relationship between pressure and temperature is used with constant volume.
P1/T1 = P2/ T2
75 kPa / 15 °C = P2 / 32 °C
P2 = 75 kPa * 32 °C / 15 °C
P2 = 2400 kPa °C / 15 °C
P2 = 160 kPa.
So therefore, the pressure of the tire on the trip home when the temperature of the road surface is 32°C is 160 kPa.

Answer:
The correct answer is -
Prokaryotic unicellular -
Eubacteria - is the domain of unicellular organisms that has a prokaryotic cell
Archaebacteria - is one of the two domains of the prokaryotic organisms that are unicellular.
Eukaryotic multicellular (autotroph) -
Plantae - is the multicellular kingdom of the eukaryotic cells and as they produce their own food by photosynthesis called autotrophs.
protists - the autotrophic protists that are multicellular comes under algae, especially red algae.
Eukaryotic multicellular (heterotroph) -
Animalia - The Animalia kingdom is the kingdom of the heterotrophic eukaryotic organism that mostly has multicellular bodies. They depend on plants or other animals for their food.
Fungi - are mostly heterotrophic eukaryotic as they get their nutrient from other organisms are mostly multicellular.
Protist - some protists are heterotrophic as well.
Eukaryotic multicellular/unicellular (heterotroph/autotroph) -
Plantae
protists
Animalia
Fungi
