Why is space cold?
Space is cold because it is a vacuum, meaning there is no air or matter to trap heat. Without any molecules to transfer heat, objects in space lose heat quickly, making it very cold.
What are examples of a vacuum?
Examples of vacuums include the vacuum inside a sealed jar, the vacuum of outer space, and the vacuum inside a vacuum cleaner.
How does a vacuum flask keep hot liquids hot and cold liquids cold?
A vacuum flask is designed with a double-walled construction. The inner wall is coated with a reflective coating to prevent radiation heat transfer, while the space between the walls is vacuum-sealed to prevent heat conduction. This insulation helps to maintain the temperature of the liquid inside, whether hot or cold.
What is the empty space where no air exist?
The term for the empty space where no air exists is vacuum. A vacuum is a space devoid of matter, including air. Vacuum is commonly used in scientific research and technology applications, such as in vacuum chambers or vacuum pumps.
How does the space vacuum cleaner work to clean up debris and dust in the vacuum of space?
The space vacuum cleaner works by using suction to collect debris and dust in the vacuum of space. It operates similarly to a regular vacuum cleaner, but is designed to function in the unique conditions of space, where there is no air to create traditional suction. Instead, the vacuum cleaner uses specialized technology to create a vacuum and collect debris and dust particles.

Why are vacuum flasks called vacuum flasks?
Vacuum flasks are named so because they have a double-wall design with a vacuum-sealed space between the walls. This vacuum insulation helps to minimize heat transfer by conduction or convection, keeping hot liquids hot and cold liquids cold for an extended period of time.
Why is outer space cold?
because the sun faces the earth while the earth is being hot Outer space is neither hot nor cold. Temperature measures the energy of atomic particles. Sense there is no atomic particles in the vacuum of outer space there is no temperature.
How can vacuum flask keep hot things hot and cold things cold?
The statement of calling it a vacuum mean there a no atoms between a space without the atoms or molecules in this space heat can not be transferred. Without this transfer of heat things can not heat up or cool down.
How much oxegyn can a astronaut suit contain?
Oxygen (O2) is necessary to the respiration and the survival of astronauts in the near vacuum of space. Astronauts does not have the breathable atmosphere on Earth in space. The space suit protects them from the lethal cold and vacuum of space by keeping him in temperature controlled and pressurized environment.
What is a vacuum in physics?
A system is said to be at a partial vacuum if it is at a negative pressure (pressure less than atmospheric pressure). When you use a straw, the partial vacuum created inside the straw is what causes your drink to travel up the straw and into your mouth.A perfect vacuum would be a space with nothing in it and a temperature of 0 degrees kelvin. Practically, however, we can only achieve and work with partial vacuums or pressure differentials. Even what we call outer space is only a partial vacuum. Rule of thumb: Nature hates a vacuum.
Can sound travle to space?
Space is a vacuum. Sound cannot travel in vacuum
Is a man made vacuum as cold as space since it has no particles to emit heat?
Yes, we can set up a vacuum chamber that can be as cold as space. Colder. We can pull a high vacuum in a small space with temperatures very near absolute zero. Within millionths of a degree or less of absolute zero, in fact. In deep space, the temperature is something on the order of 2 to 3 K. We need to mention that on earth, we have to take a lot of precautions to keep heat from radiating into our super low temperature experiments. Heat, because it can be "sent" via electromagnetic radiation, can move from any material through a vacuum to "warm" something in our vacuum chamber. It's a challenge to insulate and cool a high vacuum to near absolute zero.
Why is it cold in between the sun and earth?
Heat is caused by the vibration within atoms. Space is a vacuum and therefore there are no atoms to have any heat.
What are examples of a vacuum?
Examples of vacuums include the vacuum inside a sealed jar, the vacuum of outer space, and the vacuum inside a vacuum cleaner.

When astronauts travel in space they must wear special helmets. Why?
The helmets are part of their space suits. They do not normally wear space suits unless they are going outside the spacecraft. Since there is no air outside and it can be very cold or hot. They need the suits to breathe and to protect them from the heat or cold and the vacuum of space which would kill them.
