How do you calculate the right ascension? Convert the right ascension into decimal form using the following formula: hour + minute/60 + second/3600 = decimal value. For example, if the right ascension is 2 hours, 30 minutes and 45 seconds, then this time in decimal form is 2 + 30/60 + 45/3600 = 2.5125. Multiply […]
How do matches stay lit?
How do matches stay lit? Today’s matches create fire as the result of a simple chemical reaction. When a match is struck, friction creates heat and a flammable compound that ignites in the air. In modern matches, the two flammable compounds most often used are sulfur and red phosphorus. Can you light a match in […]
Which statement best describes a limitation of the kinetic molecular theory for a gas?
Which statement best describes a limitation of the kinetic molecular theory for a gas? A limitation of the kinetic-molecular theory for a gas is the theory assumes that particles do not experience intermolecular forces. This cannot be completely true since interactions between particles is normal. Which would you expect to have the higher melting point […]

Does aluminum cool down fast?
Does aluminum cool down fast? The heat energy stored in it increases in proportion to its mass. This allows aluminum to dump its thermal energy into the air surrounding it very quickly. So not only does aluminum not hold much thermal energy, it also dumps it super quickly. Together, these mean that aluminum foil cools […]
