QUESTION 2.1: Do you expect heat to flow into or out of the cup into the surrounding atmosphere? ANSWER: The heat flow is expected to flow out of the cup into the surrounding because temperature of the cup is more than its surroundings. QUESTION 2.2: Is the difference between the final and initial temperatures‚ T_f − 푇푖‚ positive or negative? Explain why you gave the answer you did. ANSWER: The difference between the final and initial temperatures is negative. This is due to the fact that gas

normal oxygen concentration. Like other noble gases‚ helium is an inert element‚ meaning that it has very low chemical reactivity in natural conditions. Helium doesn’t react with any other elements. It has the lowest boiling (4.216 Kelvin degree) and melting (0.95 Kelvin degree) points among all elements in the periodic table. Helium’s physical properties is very unusual. It exists only as a gas‚ except in some really extreme conditions. In liquid form‚ it is the only liquid that cannot be solidified

Thanks to Saint Anselm‚ Archbishop of Canterbury1‚ the ontological argument was born in the early 1100’s. The ontological point of view‚ according to St. Anselm‚ describes God as “a being than which no greater can be conceived”.2 St. Anselm concluded that if such being failed to exist‚ another even greater being could be conceived that does exist. This argument would be illogical‚ as no being can be greater than the greatest being. Therefore God must exist. As you can see‚ St. Anselm’s ontological

Matter is made up of atoms and molecules. Atoms and molecules are always in motion because energy. Energy forces them to contact into each other or vibrate back and forth. When this happens molecules and atoms

In the older age of the sun‚ it grows in radius and the temperature cools from around 5500 to 4900 Kelvin (1997‚ Poggee). In the start of this century‚ astronomer Ejnar Hertzsprung studied the luminosities and types of stars. Soon‚ he and American astronomer‚ Henry Russell‚ created a graphical representation comparing a star’s temperature against

The flame is the visible portion of the fire. If hot enough‚ the gases may become ionized to produce plasma.[2] Depending on the substances alight‚ and any impurities outside‚ the colorof the flame and the

Although Helium exists in the atmosphere of Earth in small quantities‚ it is one of the most common element in the universe. It is a rare gas on earth. Helium was first discovered by Pierre Janssen in the spectrum of the sun during an eclipse in 1868. It was shortly identified as an element and was named by the chemist Sir Edward Frankland and the British astronomer Sir Joseph Norman Lockyer. Helium has an atomic number of 2 and an atomic weight of 4.002602. Helium is represented by the symbol
