Practicals

1. Specific heat capacity

   • Measure mass, wrap in insulator then get initial temp. make it hotter and take readings every minute for 10 minutes
   • [triangle]E = m c [triangle][theta]

2. destities

   • liquid
     • get mass of can, add liquid and get mass, get volume of liquid and find mass of liquid then get density
   • normal object
     • get mass and lengths, times length width and height for volume, then get density
   • irregular
     • measure mass of object, fill eureka can until it pours, put object in can, measure water that falls out and calc density

3. acceleration

   • get ramp, and put car on ramp with string over a pulley. measure length and attack 1N onto the spring, let car drive down and record time, repeat
     • make sure it's same length every time
