An investigation to show... How heat affects lava flow Introduction In this investigation, I am going to heat treacle to different temperatures to see how it effects how viscous the treacle is. After heating it, I will time how long it takes to reach the bottom of a baking tray that is at a gradient of 45º. This will show me how viscous the treacle is at that temperature. Prediction For this investigation I predict that the hotter the treacle is, the less viscous it will be; therefore, taking less time to reach the bottom of the tray. Theory behind my prediction Viscosity is a property of fluids that causes them to resist flowing. All fluids have this property. The molecules of a fluid move against each, other which results in friction. The force set up by the molecules rubbing together. It is this friction that causes the viscosity of the liquid, which may also be...
