What is the relationship between the kinetic energy of molecules in an object and the object's temperature?as the temperature increases, the kinetic energy of the molecules increases
the kinetic energy always increases whether the temperature increases or decreases
the total kinetic energy of the molecules is not affected by a change in temperature
as the kinetic energy of the molecules decreases, the temperature increases
Answers
Answer: as the temperature increases, the kinetic energy of the molecules increases
Explanation: The kinetic energy of the molecules is the energy possessed by virtue of motion of the particles.
Kinetic energy of the particles is directly proportional to the temperature of the gas.
where T= temperature
R= gas constant
Thus if the temperature is increased, the molecules start moving more randomly and gain kinetic energy.
The production of the energy by the moving particle is called kinetic energy. The kinetic energydepends on the following:-
- Mass
- Velocity
The kinetic energy of every state is different i.e the kinetic energy of the solid, liquid, and gas are different. The kinetic energy of the particles is directly proportional to the temperature of the gas.
T= temperature
R= gas constant
Thus if the temperature is increased, the molecules start moving more randomly and gain kinetic energy.
Hence, the correct option is A

The bacteria in nasty environment undergoes multiple fission.
Explanation:
The bacteria is a unicellular prokaryotic organisms that are found in each and every places of the world. They can survive in extremes of temperatures and pH. They can save themselves through special processes in the extreme climates.
The bacteria undergoes multiple fission in these climates. They cover themselves up with a strong and tough capsule inside which they undergo several Binary fissions. This leads to the formation of multiple cells enclosed with a capsule.
With the return of the favourable climate, the capsule rupture and these newly formed cells come out.

Answer: grams
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number of particles. and weighs equal to the molecular mass.
To calculate the moles, we use the equation:
1 mole of Americium weighs = 243 g
Thus of Americium weigh=
Thus the mass mass in grams of a sample of Americium containing six atoms is
The mass (in grams) of the sample of Americium containing six atoms is 2.42×10⁻²¹ grams
How to determine the mass of Americium containing six atoms?
First, we shall obtain the mole of americium that contains six atoms. This is illustrated below:
From Avogadro's hypothesis,
6.022×10²³ atoms = 1 mole of americium
Therefore, we can say that
6 atoms = 6 / 6.022×10²³
= 9.96×10⁻²⁴ mole of americium
Finally, we shall determine the mass (in grams) of the americium. Details below:
- Mole of americium = 255163.41 moles
- Molar mass of americium = 243 g/mol
- Mass of americium = ?
Mass of americium = Mole × molar mass
= 9.96×10⁻²⁴ × 243
= 2.42×10⁻²¹ grams

They make food by using chemosynthesis.
Explanation:
Final answer:
Deep-water bacteria, known as chemoautotrophs, make their own food through a process called chemosynthesis, using chemicals like hydrogen sulfide from hydrothermal vents instead of sunlight.
Explanation:
Some deep-water bacteria in the ocean are known as chemoautotrophs, which can produce their own food by using chemical energy from hydrothermal vents. Unlike plants, they do not use sunlight for photosynthesis. Instead, they rely on chemosynthesis for their energy supply. In this process, bacteria convert chemicals from the vents into usable energy or food. For example, some bacteria use hydrogen sulfide, a chemical abundant in the deep ocean, for chemosynthesis. This biological process allows these deep-water bacteria to thrive in environments where sunlight is not available.
