Write the mathematical relation to calculate % error of your experimental results? -Percentage error % = measured value –accepted value x 100 Accepted value 4. Write the relation between Kelvin and Celsius scale‚ and Fahrenheit and Celsius scale. -The Kelvin and Celsius scale are the same both are one hundred of between freezing point of water and boiling point at standard atmospheric pressure. -Fahrenheit and Celsius scale it is an interval of 180 to cover

sun. Pluto’s distance from the sun gives it a large range of temperature on its surface‚ its stated as the coldest by Earth’s standards. It is so cold on Pluto that a regular theromater can not state its coldness‚ scientist have to use a Kelvin scale. Using Kelvin scale‚ Pluto’s temperture is at 44 K which is approximately -239 degrees. Its maximum reaches at 55 K ( -218 F ) and a minimum of 33 K ( -240 F ). Pluto maybe the coldest planent but surprisely‚ it has a warmer atmosphere than the surface

INTRODUCTION Thermodynamics is a branch of physical science in which deals with the relations between heat and other forms of energy. The ability to predict if a chemical reaction will occur spontaneously or non-spontaneously is an important aspect of thermodynamics. Spontaneity is determined from free energy‚ or Gibbs free energy. The equation (1) gives the relationship of how entropy (∆S) and enthalpy (∆H) along with temperature affects the amount of free energy‚ and henceforth the spontaneity

Boyle’s Law - Solutions 1) If I have 5.6 liters of gas in a piston at a pressure of 1.5 atm and compress the gas until its volume is 4.8 L‚ what will the new pressure inside the piston be? P1V1 = P2V2 (1.5 atm)(5.6 L) = (x)(4.8 L) x = 1.8 atm 2) I have added 15 L of air to a balloon at sea level (1.0 atm). If I take the balloon with me to Denver‚ where the air pressure is 0.85 atm‚ what will the new volume of the balloon be? P1V1 = P2V2 (1.0 atm)(15 L) = (0.85 atm)(x) x = 18

allows the dust to scatter and absorb all incident light. Dark nebula is most visible when in front of a very bright star as it allows the observer to see the nebula as a silhouette. The average temperature inside dark nebulae ranges within 1-100 kelvin. This temperature allows star formation to take place. Dark nebula are formed in very irregular shapes but the most common can be said to follow a serpentine type shape. Dark nebulae vastly ranges in size‚ The smallest observed being three light years

measure of how hot or cold an object is‚ and it is the temperature that determines the determines the direction of thermal energy transfer between two objects. It is a scalar quantity and is measure in degrees celcius (°C ) or kelvin (K). 0 °C is equal to -273K. Kelvin is based on the properties of a gas. Thermal energy is the receiving of energy from a hot body by a cold body when placed next to each other. Internal energy of a substance is the total potential energy and random kinetic
