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.
Avoid both scenarios by planning carefully, paying attention and arriving to the airport at the right time. As a general rule, arrive at the airport no later than two hours before your domestic flight is scheduled to depart. This is somewhat later than the typical suggestion of three hours for an international flight.
