The Effect of Temperature on The Viscosity of Glycerol Research Question: What is the effect of increasing the independent variable of the temperature of glycerol (30ºC‚ 40ºC‚ 50ºC‚ 60ºC and 70ºC) (+ 0.5ºC) using a hotplate and measured using a thermometer (+ 0.05º)‚ on the dependent variable of time (secs + 0.2) taken for 50mL (+ 0.05ml) of glycerol to flow through a 50cm3 burette (+ 0.05cm3) into a 250 mL beaker (+ 12.5 mL) measured by a digital stopwatch (+ 0.2secs)‚ therefore indicating the

Data Collection and Data Processing The experiment was on the basis of the concentration of Potassium Hydroxide affecting the temperature of water that it is dissolved in. One person stirred in the different concentrations of Potassium Hydroxide while the other measured the temperature as it rose after the pellets dissolved. At times it was difficult to ensure that the pellets were completely dissolved within the solution. Raw Data Table: The temperature of water after dissolving different

F. Why is Temperature Control Important? While most hot brushes have a high and low setting‚ it’s important to be able to have even greater control of the heat you apply to your hair. For some‚ they have brittle hair that can’t handle huge amounts of heat. Fine Hair When your hair is fine or treated‚ it needs careful application of heat. Coarse‚ Thick Hair This kind of hair needs the highest temperatures to smooth it into submission. Calista Tools Pro Grip Digital Temp Control Ionic Round

purpose-built stone heating equipment and how to use and position them safely. Hot stone heaters do vary with each manufacturer and all heaters operate in different ways. Some may take longer to heat up in relation to the water capacity (the larger the heater capacity in litres‚ the longer it take to heat) depending upon the size bought‚ that varies depending upon the number of stones to be heated. It is important to use stone heating equipment that has been manufactured for the purpose of heating

using this because the thermometer with a cork fits it and also to hold the water. Water: to use as the substance to contain the heat given off by each fuel Spirit burner: I am using this to safely burn the fuels Thermometer with a cork: I am using a thermometer to take the temperate of the water. The reason I am using one with a cork attached is to keep in as much heat as possible. Timer: I am using the timer to make sure I burn the fuel for the right amount of time Measuring cylinder: I am

follows: When the ignition‚ rotary kilns occur blasting because of low temperature‚ the reason is a low ignition temperature in the kiln‚ with coal combustion is bad‚ when the coal falls to a certain extent ‚burning fierce‚causing local concentration of heat‚ blasting phenomenon occurs. Prevention method is to maximize improve the ignition temperature‚ reducing coal consumption‚ shorten the ignition time. The rotary kiln in the application area‚ the numbers to be most cement industry. The whole process

also many of the enzymes that cause for undesired changes in the food cannot function properly at low water or no water level. But during drying there are two mechanisms which take place in the food‚ firstly heat is transferred to the food to provide sufficient amount energy for latent heat of vaporisation and secondly mass transfer is taken place as the water goes away from the food stuff (Earle‚ 1983). The Rate of drying depends on the type of food‚ the processing conditions and the design of
