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.
If you are flying international, a lot of airlines suggest that you arrive three hours prior to your departure time. Personally, because it's that early in the morning, I'd be at the airport about an hour and a half before your flight leaves (if you're flying domestic).
