Problem 27E

Calculate  and determine whether the process is endothermic or exothermic for the following cases: (a) q = 0.763 kJ and w = –840 J; (b) a system releases 66.1 kJ of heat to its surroundings while the surroundings do 44.0 kJ of work on the system; (c) the system absorbs 7.25 kJ of heat from the surroundings while its volume remains constant (assume that only P-Vwork can be done).

Step-by-Step Solution:
Step 1 of 3

Heart: ● Overview of the Cardiovascular System ○ The heart propels blood to and from most body tissues via two basic types of blood vessels calle​ rteries ​and ​veins. ○ Arteries are blood vessels that carry ​ ​ way to the heart. ○ Veins are blood vessels that carry ​ d​ ack to the heart. ○ The arteries and veins entering and leaving the heart are called ​great vessels. ● General Characteristics and Functions of the Heart ○ Blood flow through the heart is ​unidirectional ​because of four heart valves. ○ The heart is functionally two side-by-side pumps that work at the same rate and pump the same volume of blood. ■ One pump directs blood to the lungs.
