Why will insulators affect how long a test tube of hot water stays hot? Background Information I know that there are many different ways of insulating this test tube‚ shiny foil can be used because it’s a poor emitter of radiation and it will reflect escaping heat by reflecting‚ because this method is used in flasks to keep hot drinks warm. Though it is a good conductor so will lose heat through to surfaces its touching but it shouldn’t matter because it will be touching air and glass which both

Social psychologist‚ Stanley Milgram of Yale University conducted a controversial and influential experiments on study of the effect of punishment on learning. Nearly 1000 people participated in Milgram’s 20 experiments. The participants assigned to be a learner and a teacher. Milgram created an electric ’shock generator’; it ranged from 15-450 volts. The teachers were given a task to teach and then test the learner on a list of word pairs. For the first wrong answer‚ the teacher will flip the switch

Pipe Flow Experiment Purpose The purpose of the experiment is providing an opportunity to students of experience to familiarize with some key aspects of fluid flow in pipe‚ notably friction losses and verify theory. In this experiment‚ required equipment are a water tank‚ piezometric tubes‚ pump‚ a stop watch‚ empty bucket and a digital weight scale. By operating the pump to keep the water is full in the water

In this experiment‚ we planted bean plants and put stress on them by rubbing them a certain amount of times a day. This was to see how they might survive in a windy area or in an environment where they might constantly be touched or moved around. The bean plants were

As stated above‚ humans have a need to be accepted by others and for this to happen‚ each individual within the group must share the same belief as the group.An experiment by Donna Webster and Arie Kruglanski showed that dissenters who voiced their opinion were rejected by the entire group and this explains that we tend to conform to behaviors around us for the sake of not being rejected(Kruglanski & Webster‚ 1991)

The purpose of this lab was to determine if a there is a change in mass when a gas is produced and determine if gas has mass. To conduct this experiment‚ the group must be careful not to let the Alka-Seltzer tablet get wet before the bottle is closed by wiping the lip of the bottle and the cap so it remains dry‚ or risk gas escaping into the air and not being captured by the bottle. Also‚ the group must be sure to close the bottle tightly with the cap‚ because gas may escape this way as well. During

Liza Handler Experiment Background: Squid is a keystone species‚ negative effects on them can have major consequences down the line. Nearly all of the animals in the oceans ecosystems either eat squid‚ or are eaten by squid. Squids not only have a vital role in our Oceans ecological community‚ but they also are important economically. Squid is a main source of food for the tuna and hake‚ two major commercially important fish. In 2011‚ fisherman harvested a total of $100 million worth of squid

Part I - Illumination Experiments (1924-27) These experiments were performed to find out the effect of different levels of illumination (lighting) on productivity of labour. The brightness of the light was increased and decreased to find out the effect on the productivity of the test group. Surprisingly‚ the productivity increased even when the level of illumination was decreased. It was concluded that factors other than light were also important. Part II - Relay Assembly Test Room Study (1927-1929)
