Physical lab for school and collage

A hot air oven is a type of dry heat sterilization. Dry heat sterilization is used on equipment that cannot be wet and on material that will not melt, catch fire, or change form when exposed to high temperatures.

The device which is used to find the mass or weight of the given object is physical balance. This physical balance device can correct the mass of an object into milligram. The amplitude of oscillations will decrease when the beam is raised and it becomes to rest at a point which is called the resting point.
