What crushes a tightly corked tin can containing steam when cold water is poured on it?
When cold water is poured on a tightly corked tin can containing steam, the rapid cooling of the steam creates a pressure difference that causes the can to crush. The steam condenses into water, leaving a vacuum inside the can. The external atmospheric pressure then crushes the can due to the lack of pressure inside.
Water becomes steam at what degrees?
Water becomes steam at 100 degrees Celsius under normal atmospheric pressure.
How do molecules of steam exert pressure inside the kettle?
The molecules of steam in a kettle have high kinetic energy due to heat, causing them to move rapidly and collide with the walls of the kettle. These collisions create pressure as the molecules transfer momentum to the kettle walls. When the pressure inside the kettle exceeds the atmospheric pressure, the steam escapes as a jet through the spout.
At what temperature does steam form?
Steam forms when water reaches its boiling point, which is 100 degrees Celsius (212 degrees Fahrenheit) at standard atmospheric pressure.
How valid is the assumption that the initial temperature of the steam is 100 degrees celsius?
The assumption that the initial temperature of steam is 100 degrees Celsius is generally valid when referring to saturated steam at atmospheric pressure. However, it's important to consider that the temperature of steam can vary depending on the pressure or if it is superheated. Additional information or measurements may be needed to confirm the exact initial temperature of the steam in a specific scenario.
How do you calculate 25 bar steam condenstate pressure?
If the steam pressure is 25 bars the condensate pressure is at most 25 bars. Typically it is slightly less due to friction of the fluid passing through the steam traps. As the condensate approaches the condensate tank, where it is normally vented to atmosphere, the pressure decreases in the system to near atmospheric.
What exerted pressure on the piston in newcomen's steam engine cause it to move?
Steam pressure pushes the piston up. Atmospheric Pressure pushes the piston down.

What temperature does water turn to steam?
At normal atmospheric pressure, it is 100 deg C. However, water will evaporate at a much lower temperature.
Water becomes steam at what degrees?
Water becomes steam at 100 degrees Celsius under normal atmospheric pressure.
What is the steps for crushing can in cold water?
You have to fill the can with steam and then seal it closed. when you then put the can in cold water the steam will condense into water and the can will be crushed by atmospheric pressure.
What is the temperature of dry saturated steam at 510psig?
It will vary slightly with changes in atmospheric pressure, but is approximately 472ºF.
What temperature does water boil and evaporates into steam?
boiling point is a property which depends upon the atmospheric pressure. when vapour pressure of water is equal to external is called its boiling point.. if pressure is equal to atmospheric pressure ,boiling point is 100 degree celcius.
How do molecules of steam exert pressure inside the kettle?
The molecules of steam in a kettle have high kinetic energy due to heat, causing them to move rapidly and collide with the walls of the kettle. These collisions create pressure as the molecules transfer momentum to the kettle walls. When the pressure inside the kettle exceeds the atmospheric pressure, the steam escapes as a jet through the spout.
What is marcet boilers?
The Marcet Boiler is used to investigate the relationship between the pressure and temperature of saturated steam in equilibrium with water at all pressure levels between the atmospheric pressure and 1100 kPa.
At what temperature does steam form?
Steam forms when water reaches its boiling point, which is 100 degrees Celsius (212 degrees Fahrenheit) at standard atmospheric pressure.
What is pressure compounding?
Pressure compounding is a method used in steam turbines to improve efficiency by dividing the pressure drop across multiple stages. This involves passing steam through a series of turbine stages, with each stage operating at a different pressure level. By reducing the pressure drop across each stage, pressure compounding helps to extract more energy from the steam and increase the overall turbine efficiency.
