How is petroleum different from natural gas? Explanation: Petroleum gas is mainly C3 and C4 based (propane and butane), whilst natural gas is predominantly C1 and C2 (methane and ethane). Petroleum gas is generally produced via the cracking of naphtha, which is one of the components separated during crude oil refining. Will gas be phased […]

What changes our climate? These have been caused by many natural factors, including changes in the sun, emissions from volcanoes, variations in Earth’s orbit and levels of carbon dioxide. Global climate change has typically occurred very slowly over thousands or millions of years. How hot has the Earth gotten? Earth’s average temperature has risen more […]

Does turning off your phone stop radiation? Toggle data on and off A cellphone’s data radios (2G, 3G & 4G) emit the most radiation. If you are travelling with your phone in your pocket, turn off mobile data. That switches off the radiation emitting radios. Turning data on and off is just a toggle in […]

Do resistors reduce voltage? A resistor has the ability to reduce voltage and current when used in a circuit. The main function of a resistor is to limit current flow. Ohm’s law tells us that an increase in a resistors value will see a decrease in current. To reduce voltage, resistors are set up in […]

What is an example of a miscible solution? Two liquids that appear to mix completely together are said to be miscible. Water and ethanol are one example of a pair of miscible liquids, because you can take any amount of ethanol and mix it with any amount of water and you will always end up […]

What is the advantage of a light microscope over an electron microscope? Electron microscopes have two key advantages when compared to light microscopes: They have a much higher range of magnification (can detect smaller structures) They have a much higher resolution (can provide clearer and more detailed images) Which of the following is an advantage […]

Can you appeal a de novo hearing? The established case law allows for a De Novo (meaning ‘new’) hearing as if the original hearing had not occurred, and more importantly, allows an individual to include testimony from outside parties and witnesses. If the court denies a party’s ability to a full hearing it could lead […]
