The molar heat capacity is the heat capacity per unit amount (SI unit: mole) of a pure substance and the specific heat capacity, often simply called specific heat, is the heat capacity per unit mass of a material.
Long TSA lines this summer. The TSA is expecting long lines at their security check points during the busy summer travel season â especially when youâre traveling in the morning. The TSA recommends arriving at the airport at least 2 hours early for domestic travel and 3 hours early for international travel.
Usually for an international flight (out of europe) you should be there about 3 hours before the flight. for a European flight, u can be there 2 hours before the flight. But to be honest there is no point turning up that early unless you plan to go shopping at the airport, otherwise you will wait around for ages.
