A: In 1976, Vanguard introduced individual investors to the first mutual fund designed to mimic the S&P 500 Index. Today it is known as the VanguardÂ® 500 Index Fund. Nowadays, most investment firms, including Fidelity and Schwab, offer an S&P 500 index fund.easonality of S&P 500 and Mega Cap Stocks. A look at whether the S&P 500 and specific stocks tend to rally in October, November and December, and how often they do.
Â· Temperature affects osmosis, because the greater the temperature, the greater the energy (which must be heat), the faster the molecules under the influence of the heat will move, and the faster they will diffuse across the membrane. This isn't the only worry, because heat can have a physically detrimental affect on this experiment as well.
As you increase the temperature the rate of reaction increases. As a rough approximation, for many reactions happening at around room temperature, the rate of reaction doubles for every 10Â°C rise in temperature. You have to be careful not to take this too literally. It doesn't apply to all reactions.HE EFFECT OF TEMPERATURE ON REACTION RATES This page describes and explains the way that changing the temperature affects the rate of a reaction. It assumes that you are already familiar with basic ideas about the collision theory, and with the Maxwell-Boltzmann distribution of molecular energies in a gas.
