Why does a group of warmer atoms take up more volume than a group of cooler atoms?

Answers

Answer 1
Answer: Warmer atoms expand. There is also more movement. This is also explained when putting it into terms with solid vs. gas. In a solid, the atoms vibrate, but they can't move very far because there is not a lot of space between them. In a gas, on the other hand, the atoms are spread apart, and they move very fast. Putting it into context with water, the steam (gas) version is hot, and the ice cube (solid) version is cold. Which one moves more freely? The gas.

You place ice cubes into a glass of lemonade what happens to make the lemonade to get cold

Answers

When we place ice cubes into a glass of lemonade then transfer of thermal energy from lemon water to ice cubes takes place.

What is transfer of energy?

Transfer of energy means the transformation of energy from one form to another form or from one place to another place.

When we place ice cubes into a glass of lemonade, as we know that the temperature of ice cubes is low and it has low thermal energy and the temperature of lemonade is high and have a high thermal energy as compared to ice cubes. In this condition thermal energy goes from lemonade to the ice cube till they both have same thermal energy.

Hence, transfer of thermal energy takes place.

The heat energy from the room temperature lemonade transfers to the cold ice cubes, causing the temperature of the lemonade to drop and the temperature of the ice cube to rise until they are equal to each other.

Which of the following is not part of Dalton's atomic theory?

Answers

The scientist thought that the atom was the smallest particle in the universe is John Dalton. He established the atomic theory which consists of five; elements are made of extremely small particles called atoms, atoms of different element have different sizes, mass and physic – chemical properties, atoms cannot be divided further, destroyed or created, atoms can combine to form compounds and in chemical reaction, atoms can be combined, separated or rearranged.

The cell wall is a rigid structure that surrounds plant cells. The materials found in the cell wall protect the plant cells and give plants structural support.Which conclusion can be made given the above information?
The structures of different types of cell organelles are similar.

The functions of most cell organelles are hindered by their structures.

The structure of a cell organelle is directly related to its function.

The function of a cell organelle can change over time.

Answers

Answer:

The correct answer will be option- The structure of a cell organelle is directly related to its function.

Explanation:

The cell wall is a layer formed around the plasma membrane of the plant cell which helps plant cell by providing stiffness and support to the cell. This cell wall provides protection to the plant cells.

Since the presence of cell wall around the plasma membrane shows that it has a specific function and serves an important function of the plant cell, similarly the structure of various organelles present in the cell is related to their function. The best-known example is the inner folding of the mitochondria called cristae to increase the surface area.

Thus, the selected option is the correct answer.

The structure of a cell organelle is directly related to its function because for example, us. Humans have cells throughout their body. In fact, these cells are all the same. But these cells don't perform the same tasks or else we wouldn't be able to walk, sleep, talk, breath, and bend the way we do.
