Temperature and Thermometers The Temperature of an object is a measure of the hotness or coldness of that object. An alternative way to think of temperature is to say that “the temperature of an object is a number – on some manmade scale – that indicates the hotness of the object”. ‘Hotness’ in turn is a measure of the kinetic energy of the molecules of the material. Note: You must use the term ‘hotness’.* The SI unit of temperature is the Kelvin (K)* Relationship between degrees Celsius

This is a primary instrument for instrument flight and is also useful in conditions of poor visibility. Pilots are trained to use other instruments in combination should this instrument or its power fail. The airspeed indicator shows the aircraft’s speed (usually in knots ) relative to the surrounding air. It works by measuring the ram-air pressure in the aircraft’s pitot tube. The indicated airspeed must be corrected for air density (which varies with altitude‚ temperature and humidity) in order

1. OVERVIEW System is a collection of interrelated component (subsystem) that function together to achieve some outcomes. It also is a set of object and relationships among the objects viewed as a whole and designed to achieve a purpose.

Due to the fact that it would be closer to the light source‚ the light would be slightly more intense‚ therefore the rate of photosynthesis would be slightly more advanced‚ causing a lower absorption.

when determining what topic you would like to write about and how you will go about it. Free writing is like an unstructured outline‚ and once you determine the specific ideas you’d like to pursue‚ you can dispose of all other irrelevant information. B. Researching Researching is another important component of prewriting. Once you determine your topic‚ you will obtain information from outside sources such as encyclopedias‚ the internet‚ books written on the subject in order to form the

EFFECT OF ROOM TEMPERATURE ON THE BURN-RATE OF A CANDLE BURNS Have you ever wondered whether a candle burns more quickly on a hot day‚ than on a cold day? Or is it the other way around? This science fair project was carried out to compare how quickly a candle will burn at different room temperatures. The experiment was done by measuring how much of a candle will melt in 30 minutes when placed in an environment with surrounding temperatures of 20°C‚ 25°C and 30°C. Hypothesis A candle in a colder

Psych rotations has been a hug revelation for me. I was terrified to start psych rotations‚ but it is not bad at all. My first week scared me the most. I was walking to the entrance and I glance over into a patient’s window and I see a patient with long black hair staring at me out of their window. That was the first impression that it got and scared me. But as I got into the unit and took a tour‚ my nerves started to ease. The first couple of weeks I played it safe and chose the patients with mood

Mental Rotation Lab Report: PSY 405 – Spring 2012 Deng Jichun Introduction The purpose of this experiment was to confirm the theory that we create picturelike representation of perceived visual stimuli‚ and we can also mentally rotate the representation to a known “upright” position. The reaction time increases linearly according to the angle of the rotation‚ regardless of their complexity (Cooper‚ 1975). In some circumstances‚ we snap the perceived visual stimuli and create

ABSTRACT By calculating the difference in the mass of the hydrate copper (II) sulfate and the anhydride we were able to determine the mass of water in the hydrate. This information was then used to determine the empirical formula of the hydrate‚ defined as a compound formed by the addition of water to another molecule. In the first trial‚ the mass of water in the hydrate was determined to be 0.41 g‚ while in the second trial the mass of water was 0.52 g. Moles of water associated with a single

The speed of light (meaning speed of light in vacuum)‚ usually denoted by c‚ is a physical constant important in many areas of physics. Its value is 299‚792‚458 metres per second‚ a figure that is exact since the length of the metre is defined from this constant and the international standard for time.[2] This speed is approximately 186‚282 miles per second. It is the maximum speed at which all energy‚ matter‚ and information in the universe can travel. It is the speed of all massless particles and
