When two or more solid substances are mixed together they liquefy is called? In chemistry, a mixture is a material system made up of two or more different substances which are mixed but are not combined chemically.

How is energy transferred from one object to another?
How is energy transferred from one object to another? The two ways that energy can be transferred are by doing work and by heat transfer. Can an object have work? In the physics sense, work is never something an object has. It is only something that one object does to another. Work changes the amount […]

Is forced hot air unhealthy?
Is forced hot air unhealthy? The biggest downside of using a forced air heating system is that it leaves you vulnerable to inefficiency stemming from ductwork problems. If your ductwork is well-designed, expertly installed, and kept in prime condition, then you’ll be able to heat your home quite efficiently. Is forced air heating cheaper? Other […]
What does the slope of position time graph represent?
What does the slope of position time graph represent? The slope of a position graph represents the velocity of the object. So the value of the slope at a particular time represents the velocity of the object at that instant. What is a real world example of negative slope? A simple example of negative slope […]
