Using Charles’ Law to Determine Absolute Zero Background Info It is noticed that in this lab‚ as the temperature of the water in the beaker is increased‚ the distance between the pipette and water plug increases. When this distance increases‚ the volume of trapped gas also increases. This relates to Charles’ Law as it shows that the volume of a gas is positively proportional to temperature. Theoretically‚ absolute zero is the lowest possible temperature‚ where all molecules have the least possible

To begin with‚ you need to be a good listener. Make sure you understand what is being said and what is being asked. When you take the wrong instructions you make the unit you are working for inefficient. Attend to details. Make sure every work

The list is near endless when it comes to how physics can affect our daily life. For example‚ just walking is a part of physics in our daily life. Here is a list of some of the ways physics touches our daily life: 1. Motion can be explained using physics as part of the laws ofmechanics and thermodynamics. 2. When we eat‚ we convert food to mechanical energy. While this is aphysics concept‚ eating is also chemistry because the food is digested under a chemical reaction that is then able

To investigate the relationship between surface area : volume ratio and heat loss. INTRODUCTION: The aim of this experiment is to investigate and find the relationship between heat loss (of water) and surface area to volume ratio of animals. To investigate this‚ we are going to use three flasks of different volume (as the equivalent the animals) and thus different surface areas filled with water. BACKGROUND: Surface Area : Volume Ratios We will be using the following formula for calculating

Calorimetry 1. How many calories would it take to raise the temperature of 200 g of water 100oC? 2. It takes 23.5 J to raise the temperature of 10.0 g of silver by 10oC. What is the specific heat of silver? 3. A 255 g quantity of gold is heated from 28oC to 100oC. How many joules of energy were used? (specific heat of gold = 0.13 J/goC) 4. What will be the final temperature of 5.00 g of silver at 37oC if it gives off 25.0 J of heat to the surroundings

James Howard Kunstler begins his essay by quoting a well-known author and columnist‚ Thomas Friedman‚ who states that globalisation is a wonderful fixture of society‚ and that it is here to stay. Globalisation refers to an increased openness of national borders to the movement of trade‚ products‚ and money in the past forty years or so. Kunstler however‚ is strongly opposed to this point‚ and believes that globalisations will soon be a thing of the past. He believes that this state of Globalisation

Measuring the Enthalpy change of combustion Abstract This simple experiment is carried out to show the difference in the enthalpy change of combustion between two fuels‚ hexane and methanol. These fuels are individually weighed before and after used as heat source to heat water in a calorimeter. The result is used to find out amount of heat transferred by the fuel‚ amount of fuel used and the enthalpy change of combustion. Introduction Enthalpy change of combustion is the enthalpy change when
