Results The diameter of the cylinder (D) is 0.01m and the length of the heater (L) = 0.07m. The emissivity of the surface was 0.95 and the Stefan Boltzmann constant was 56.7x10-9 Wm-2K-4. The room temperature was assumed to be 25°C which is 298.15K.

substances catch fire at a different temperature. The lowest temperature at which a substance catch fire is called its ignition temperature. Combustible substances do not catch fire or burn as long as its temperature is lower than its ignition temperature. Now let me do an activity which tells you why reaching ignition temperature is necessary to burn an object. You know that paper catch fire with a flame. Let me

Heat‚ Temperature‚ and Phase Changes Assessment Practice Answer This graph shows what happens to the temperature of the water‚ while it was boiling in a kettle‚ as heat energy was being added to it and what the water was doing will it began to warm and change states. During a phase change‚ the temperature remains mainly constant. This occurs because the heat energy is used to break the bonds between the ice molecules as they turn into a liquid phase. It is possible to constantly

EXPERIMENT-1 Pressure-Temperature Relationship for Steam OBJECT: The objective of this experiment is to determine the relationship between saturation pressure and saturation temperature of the wet steam. APPARATUS: Pressure-temperature apparatus with pressure gauge and thermometer. [pic] THEORY: In order to determine the relationship between the saturation temperature and pressure of wet steam it is necessary to obtain a number of corresponding values of the

The aim of this experiment was to investigate the effects of salt type and concentrations on the rate of heating and the boiling point. Then from this data make a conclusion which salt type and concentration is the most energy efficient at heating water to its boiling point. It was hypothesised that highest concentration of MgCl2 was going to be the most energy efficient at heating the solution to its boiling point. This is because MgCl2 has the lowest specific heat capacity thus will use the least

if an egg will float in salt water. The question is how much salt is needed to be added to the water to make the egg float. The problem is that no one knows how much salt is needed to make an egg float. Hypothesis It will take at least three teaspoons of salt to be added to the water for the egg to float. The reason why I think three teaspoons of salt will need to be added to water for the egg to float is because the egg a density that is lower than the density of the salt water.

stories that contain the eight formal elements she identifies as prerequisites for the genre. Chief among them is the element of betrothal––or‚ as it is more colloquially understood‚ the “happy ending.” When considering Patricia Highsmith’s The Price of Salt‚ there is some room for debate as to whether the book can truly be called a romance. The novel details the courtship of two women in the 1950’s––Carol Aird‚ a wealthy homemaker in the midst of an ugly divorce‚ and Therese Belivet‚ a naïve‚ struggling
