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.
I think 3 hours is ridiculous and 2 hr. should be more than adequate -- even 1 1/2 should be fine. Every time I've left on an international flight from BWI I had no line at all and ended up just sitting around. It took me no time at all to get to the gate. I'm not sure why they always say 3 hours. I think they use it as a blanket rule for all international flights.
