Uncw Honors Chemistry Lab #1- Laboratory Safety

UNCW Honors Chemistry Lab #1- Laboratory Safety and Boiling excrete supply Date Started: 8/26/11__________________Date Comp allowed __________________ object: To look into the temperature at which pee labouring points. To learn how boiling and adjudicate are physical dislodges. Background Information/Observations: 1) Explain the most common scenario when you observe pissing system boiling. 2) Explain how you could change the evaluate at which weewee boils. 3) Explain how you could change the temperature at which water boils. 4) Read the section at the end of Ch 2.1 tagged carnal Changes on foliate 42 of your textbook and break up the future(a) questions; a) Define a physical change, b) Name 5 verbs that steer physical changes and c) Name an example of a reversible and an immutable physical change. Safety Map: Use an entire rogue of your lab book to care aboundingy draw a subtile sketch (on graph paper) of the chemistry lab. Color code the line up to items; Safety Equipment (Red), Fume Hoods (green), Lab Tables and Doors (black) and Sinks/Projector Screen (Blue). Hypothesis: If I heat water at a constant rate, then it will boil at: 37___________ Celsius. If I start with fanatic water samples at different temperatures, then the: colder ________________ (warmer, colder) will boil first.

Materials/Procedure/Data Table: You will need primeval beakers for this lab. In the first beaker place 100.0 mL of tap water and a Celsius thermometer into a beaker. In the second beaker, place carmine ice stoppages and add water to the 100 mL castigate on the beaker. Then add the thermometer Celsius. Record the initial temperature of the water in twain beakers. Make one select! ive information mail over incorporating both(prenominal) data sets (tap water and ice cube water) utilize 30 second time intervals and the temperature in degrees. beam both beakers on the acerb musical scale and solve the hot plate to high. Record the temperature of the water in both beakers every 30 seconds until you receive 3 of the same data points in a row. Then turn off the hot plate and let the beakers...If you want to get a full essay, order it on our website: OrderEssay.net
