Determination the MW of a volatile liquid

 A-Level Chemistry: Getting out the steam kettle to heat up a gas syringe to 373K then inject a known mass of a volatile liquid into the syringe and measure its volume  at 373K then use PV=nRT to calculate the number of moles for that mass and from that the MW

Synth Setup

 Setting up my synth to do some background music. I can use both a hardware and a software setup; sometimes, I use the software to make the hardware sound different. Still looking for that signature sound. One day, I might stumble across it.

Rates of Reaction

GCSE Chemistry Tuition: When covering revision for a test, nothing can beat the @pascoscientific colourimeter to create a concentration reaction curve this fast. In just 20 minutes, we had done 5 different concentrations of thiosulfate vs acid and got these results.

 

Foundation Maths

 GCSE Foundation Math Tuition: We are learning probability concepts - probably not for the first time. We are linking the real world with the world of Math - making some concepts easier to retain.

Momentum

 GCSE Physics - Learning all about momentum mass x velocity and how the momentum before a collision is the same as the momentum after the collision.

Terminal Velocity in Glycerol

GCSE Physics Tuition: We are looking at Terminal velocity using glycerol as a medium. Using the @pascoscientific rotary motion sensor and capstone, we could easily see how the weight accelerated and then slowed to a terminal velocity. The cord has no measurable effect.
