Tesla is now a battery company first, and a car company second. Tesla isnât creating a new market, though. The Tesla Powerwall is not exactly the first home battery of its kind. Others exist. Most home batteries function approximately like this: batteries charge at night, when utility companyâs rates are the lowest, and can then be switched on in the morning so homeowners can enjoy that cheap energy throughout the day.
Charlesâs Law states that at constant pressure, the volume of a given sample of a gas is? directly proportional to the absolute (or Kelvin) temperature. Suppose a sample of oxygen has a volume of 135. mL at a temperature of 50.0ÂºC.
According to Avogadro's law, as the number of moles of gas increases the volume also increases. Explanation: Avogadro Law gives the relationship between volume and amount when pressure and temperature are held constant. Remember amount is measured in moles. Also, since volume is one of the variables, that means the container holding the gas is flexible in some way and can expand or contract.
