Vocabulary: • Conduction- the passage of energy‚ particularly heat or electricity‚ through something • Rate of Change- the ratio of the difference in values of a variable during a time period to the length of that time period • Calorimeter- an apparatus for measuring the amount of heat given out or taken in during a process such as combustion or change of state. The measurements are often made by observing the amount of solid liquefied‚ or liquid vaporized‚ under set conditions. • Conservation

To belong or not to belong is the feeling of being excluded or included by a group‚ person‚ place or community. I believe to belong on many levels you must first feel you are entitled to belong. This may come about through your personal experiences and how you tuley feel about yourself and your self worth. In the illustrated story ’The Sneetches’ illustrated and written by Dr. Suess he demonstrates individuals within a group desperately seeking approval of another group they are made to believe

What stereotypes would you want to make sure to avoid? The importance of using their other senses to “see” what the world looks like. Those of us who can see are not aware of the importance of smell‚ and touch. We see with our eyes‚ while blind people see with their hands‚ ears‚ nose‚ etc. Blind people are not always unable to see everything

6 report Anita Dey Thursday 8am Abstract: We recently performed a liquid nitrogen experiment in finding the Latent heat of the substance. We isolated two parts of the experiment in order to find out how much evaporation of the liquid nitrogen was from the surroundings B and how much evaporation from the electricity G. 1. When a substance is undergoing a phase transition‚ more heat (energy) is being added to the Substance but its temperature (a way of measuring its energy) is not changing. Where

Ailine Veiga Question: what is the heat of fusion of ice? Hypothesis: To get the heat of fusion of ice we need to determine the Energy it takes to melt the ice and also the mass of the ice and determine the heat of fusion. To determine the mass of the ice melted (m) we start by determine the volume of the water generated when the ice melted. This is the difference between the final volume (v2) and the initial volume (v1). Using the density of water (1.0g/mL)‚ this volume can be converted into mass

lab‚ we are now able to calculate the molar heat of combustion for paraffin‚ since we have the difference of the mass in candle before/after and the periodic table of elements (for converting g to moles of paraffin). Molar heat of combustion = (kJ of heat)/(mole of fuel) However‚ we do not know how much heat was released nor the mole of fuel (paraffin). In order to find the amount of heat released‚ we use the formula: g=mcΔT. Here‚ g represents the heat‚ m represents the mass of water‚ ΔT represents

belongs to. Humans are by nature sociable beings that must learn to cooperate for peaceful existence to occur but are also individual personalities who seek their own self fulfilment. Belonging to groups; family‚ social or environmental groups‚ can have immeasurable benefits. But while groups do provide one with a sense of identity‚ security and protection it can however result in sacrifices to selfhood and can entail certain inevitable costs. Groups tend to be self policing and apply criteria for membership
