Temperature

intermolecular forces of attraction present; and the nature and strength of intermolecular forces determine the variations in boilingpoints of organic compounds. The boiling point of a liquid is the temperature at which its vapor pressure equals the external or atmospheric pressure. At this temperature, every molecules of the liquid acquire enough kinetic energy to overcome the intermolecular forces attracting them to the other molecules. Therefore, boiling points…

How TPO Roofing Works TPO Roofing Thermoplastic Olefin (TPO) roofing membrane is often regarded as one of the most efficient and economical roofing alternative to PVC roofing. This single ply roofing system is made out of thermoplastic polyolefin membrane, which consist thermoplastic polyolefin top fly compound, TPO polymer base and polyester-reinforced fabric center. TPO fabric also uses fillers made out of carbon fiber, Metal Oxy Sulfate, wollastonite and fiberglass as well as EPDM and…

Prepare 100ml of water into a beaker then cover it with an aluminum sheet. Poke a hole through the aluminum with the skewer and place your thermometer in (make sure the hole isn’t too big or you’ll let some of the steam escape. Record the initial temperature of the water. Prepare your retort stand with your ceramic container at the base of the stand. Position…

you're shivering or sweating consider it that the hypothalamus is trying its efforts to get your Body to the average temperature. Last of the brain is the cerebrum. The cerebrum is brainy part of the brain. It's also pretty large, taking up 85% of the brain's weight.Additionally the cerebrum controls your voluntary muscles (the muscles that control your the movements if you wish to a action.) the memories that you made live in The cerebrum ( the pair short term and long term). Scientists have…

WHEATSTONE BRIDGE CIRCUIT – used to measure temperature. 2 types of ratio meter circuits * Moving coil ratiometers *…

however, is not perfect. There is a degree of randomness that is noted in terms of the position of the ruler, as well as, the specific lengths used to measure. At the time of the experiment, the wind was fairly strong, thus capable of altering the temperature within the glass containers slightly; causing the contents on the inside to move, including the thermometer and the soil. This may have modified the outcome marginally. Also, an uncertainty comes from the length of time used in between…

Aim The aim of this practical is to measure the effect of volume, density and temperature. It is also help to be familiar with variety of common laboratory technique. Materials Weighting scale Container with lids 20 and 10 ml Volumetric pipette Beaker Thermometer Test Tubes Volumetric flask Natural Rubber Pipette Filler Micropipette tips Tips boxes Method There are two pipette, choose one which you using in whole practical. Label and weight accurately, to 4 decimal places. Collect…

such as northern Scandinavia is characterized by cold and long winters, and short and cool summers. Precipitation is generally in the snow form and annual precipitation for these regions is less than 20 inches. Temperature has a major influence on aquatic life in these regions. Temperature decreases in the winter and as sea ice solidifies, the amount of pore pace within the ice is reduced and the salinity increases. Organisms must be adapted to prevent the growth of ice crystals in their bodies.…

you need to know about placing your thermostat in the ideal spot. Keep Out of the Heat Your thermostat senses the indoor temperature and makes the necessary adjustments to your unit. If you place the thermostat in direct sunlight or near heat-producing appliances, the unit will think the house is hotter than it actually is. This make it harder to reach your preferred temperature and causes the air conditioner to work harder, putting a lot of undue strain…

transfer heat energy all around the world. Cold ocean currents are found around the polar regions and move in the direction of Equatorial regions where there are high temperatures to stabilise those temperatures. Warm ocean currents are found around the Equatorial regions and move towards the Polar regions where the temperatures are low to stabilise those…
