HEAT 4.1 UNDERSTANDING THERMAL EQUILIBRIUM 1. Define: The measure of the degree of hotness of an object. (a) Temperature Measured in SI unit Kelvin‚ K A hot object is at a higher temperature than a cold object. Form of energy‚ measured in Joules‚ J (b) Heat Heat is transferred from hotter object (higher temperature) to colder object (lower temperature) When an object is heated‚ it will absorb heat energy and the temperature will increase. When an object is cooled‚ it will release heat energy and

various properties which all relate to each other when determining the characteristic of a certain substance. One of such properties is heat capacity‚ which is the amount of heat energy required to raise the temperature of a substance by one degree Kelvin. Mathematically‚ it is ∁ = q∆T ‚ where q is the amount of heat absorbed by a substance and ΔT is the change in temperature measured. When substances absorb heat‚ their molecules translate‚ rotate and vibrate due to the rise in temperature . As

The differences in the characteristics of states of matter are given in the following table. S. No. | Solid state | Liquid state | Gaseous state | 1. | Definite shape and volume. | No definite shape. Liquids attain the shape of the vessel in which they are kept. | Gases have neither a definite shape nor a definite volume. | 2. | Incompressible | Compressible to a small extent. | Highly compressible | 3. | There is little space between the particles of a solid. | These particles have a greater

Gilbert‚ an Englishman‚ experimented with magnets to learn and understand their behaviors. Gowin Knight‚ on the other hand‚ rubbed magnets on iron bars to create super magnets. This magnetized compass needles for much longer periods of time. Lord Kelvin corrected this by using small magnets that surrounded the compass and prevented deviation. The small magnets were known as corrector magnets (Travers 155). Many different compasses have been invented‚ with various uses‚ but some stand out more than

would be the volume of the balloon? * Vf = (2.0 L)(3 atm)/(0.5 atm) Vf = 6 L/0.5 Answer: 12 L * Example #1: A gas is collected and found to fill 2.85 L at 25.0°C. What will be its volume at standard temperature? * Answer: convert 25.0°C to Kelvin and you get 298 K. Standard temperature is 273 K. We plug into our equation like this: * * Example #2: 4.40 L of a gas is collected at 50.0°C. What will be its volume upon cooling to 25.0°C? * Answer: convert 50.0°C to 323 K and 25

Viola’s Soliloquy Assignment Kelvin Park October 19‚ 2009 In William Shakespeare’s “Twelfth Night” act II‚ ii 17-41‚ Viola makes her first soliloquy after realizing that Olivia has fallen in love with her. Shakespeare uses this literary tool - in which a character talks to himself or herself or reveals his or her thoughts without addressing a listener – to create dramatic irony in the play. The audience here learns information about the said character that is unknown by the other characters

degrees Fahrenheit‚ and the density was only 10% of that of water. At this temperature stable atoms were still not able to form. The interactions between electrons and photons continued for 300‚000 years‚ until the universe had cooled to 6000 k (Kelvin)‚ roughly the temperature of the surface of the Sun‚ and the photons were becoming too weak to knock electrons off atoms. Over the next 500‚000 years the background radiation decoupled‚ and had no more significant interaction with matter. The Big

Leadership and Power Paper L’enrico Rucker LDR/300 August 28‚ 2013 KELVIN SUAREZ 1. We have described power as the capacity to cause change and influence as the degree of actual change in a target’s behaviors. Ho Ching’s power as a leader has been recognized by many‚ but would you describe Ho Ching as an influential leader? Why? Yes Ho Ching would be an influential leader because she has the capabilities to persuade others to follow her lead 2.Based on the excerpt
