P6 LAB EXAM

• What is the title of the activity 6

  Coefficient of Linear Expansion
• Parts of Calorimeter

  • stirrer
  • hole for thermometer
  • inner cup
  • fiber ring
  • outer calorimeter
• Title of activity number 8

  Heat of Fusion of Ice and Heat of Vaporization of Water
• at a normal atmospheric pressure, heat transfer Q in a phase change is

  Q=+-mL
• the plus sign

  is when heat Is absorbed or entering
• the minus sign 


  is when heat is leaving
• when solid changes to liquid or liquid to solid, L is called

  heat of fusion denoted by Lf
• for ice Lf is

  3.34x10^5J/Kg at 0 degree celsius
• freezing temperature is the same as the

  melting temperature
• at this unique temperature, the liquid and solid phase can coexist in a condition called

  phase equilibrium
• when liquid changes to gas or gas to liquid, L is called

  heat of vaporization denoted by Lv
• Objective of activity 8

  to determine the heat of fusion of ice and heat of vaporization of water by calorimetry
• title of activity 9

  Standing Wave Motion
• m is the

  mass of the string whose length is L.
• When a wave is reflected by a fixed point at the end of the string,

  the appearance of the resulting motion gives no evidence of two waves traveling in opposite directions.
• The points that remain always at rest are known as

  nodes
• The points that remain always at rest are known as

  antinodes
