NO. If you look at the parts section of their website, such as the link below for one example, you will see they have both whistleing (on-off steaming) and non-whistleing (constant steam) vent weights for most models. It appears you also need to buy the proper vent tube to go with it as well.
While all Crock-Pots are electric cookers not all electric cookers are Crock-Pots. Crock Pot is a US trademark name that is sometimes used generically to refer to all electric cookers.
Yes, barometric pressure is the same as atmospheric pressure. Both terms refer to the pressure exerted by the weight of the air in the Earth's atmosphere.
yes
A substance can boil at a higher temperature when the external pressure is increased. This phenomenon is seen in pressure cookers, where the higher pressure raises the boiling point of water. The substance requires more energy to overcome this increased pressure and reach the higher boiling temperature.
The majority of it is, yes. But things like Popcorn chicken and Snack patties aren't. They are cooked in the same deep fryer cookers that the chips are cooked in, along with bacon occasionally.
Air pressure and atmospheric pressure are the same things, just called differently. It refers to the weight of air being exerted on an object.
the force exerted onto a surface by the weight of the air
The pressure inside the bag is the same as the pressure outside.
No, fluid pressure increases with depth due to the weight of the overlying fluid pushing down. This is known as hydrostatic pressure.
At a given depth in a liquid, the pressure is exerted equally in all directions because the weight of the liquid above that depth creates the pressure. This means that the pressure at any point is determined by the weight of the liquid column above that point, regardless of the direction. So, the pressure is the same in all directions at a given depth in a liquid.
No, it will be greater Imagine pressure as the weight of a column of water over an area, typically one sq. in. So the deeper you go, the greater the weight, the greater the pressure.
Both electric skilles and electric cookers operate on the same type of cooking element but the utensil itself is different. However, a electric skillet is the same utensil as a skillet but uses the electric element to heat the food and the electric cooker is similar but it is more in the shape of a pan.
