Beverly Hearst IB SL Physics Rate of Vaporization Design Lab Research Question: How does changing the surface area of a sample of water affect the time taken for the water to boil? Background: By changing the containers of the water‚ the surface area of the water is thus being modified as the same volume of water is spread out over smaller or larger surfaces. The measure being compared is the time each sample of water will take before it reaches the boiling point‚ 100 C°. The relationship

Chapter 13 – States of Matter Pressure (P) – the amount of force per unit area. Pressure=F/a or P=F/a Pascal’s Principle “Any change in pressure at a point on a confined fluid is transmitted throughout the fluid”. Any change is transmitted throughout the fluid. Buoyancy & Archimedes Principle “When an object is submerged in a fluid‚ it displaces a certain volume of that fluid. The amount of force pushing upward on the object is equal to the density of the fluid (Ï) times the acceleration

Calculations- 1. Main Show Tank Calculation: The main show tanks radius is 70 feet. Based on that the tank is a sphere-shaped and we have to find the volume‚ I used the formula for the sphere volume which is: V= 4/3(3.14 x r^3) V= 4/3(3.14 x 70^3) V= 4/3(1‚077‚020) V= 1‚436‚026.66666... V= 1‚436‚027 But I have to find the volume of the quarter sphere-shaped‚ so: V= 1/4 x 1‚436‚027 V= 359‚007 The volume of the quarter-shaped tank is 359‚007 cubic feet Holding Tank Calculations- 2.

Nuclear Power Stations 8.4.1: The firing of neutron at a heavy nucleus may result in the nucleus splitting‚ releasing free neutrons and lighter nuclei; which can then collide with other nuclei and resulting in the same process. This is a fission chain reaction. 8.4.2: In a fission reaction‚ if you can remove the emitted neutrons from the fissionable material‚ then you can control the rate at which the chain reaction proceeds. A fission reaction whereby the reaction is allowed to proceed without

Energy: the ability to do work. Work= force x displacement. Power=energy/time Power is measured in watts or horsepower. Joules/sec=watts 1hp=746w=1kw Basal metabolic rate 2000kcal/day= 100w Batteries store energy in chemical form. They release energy by pumping electrons’ through wires from the minus pole to the plus pole. Devices inbetween convert this energy to another form‚ Efficieny- e.motor=85%‚ combustion= 20% Hydrogen is not a source of energy but a means of transportation Types of energy:

Physics (Thorpe Park Trip) Report: On Monday 8th October our physics class went on a physics trip to Thorpe Park to look at the different ways in which a roller coast works. This report will be looking at the G forces acting on rides‚ the launching systems and breaking systems. The particular rollercoaster which I have picked to look into more detail in is “Stealth” which is located in Thorpe Park. Stealth: Stealth was originally designed by Werner Stengel. Stealth reaches a height of 205 feet
