The unit of pressure is the Pascal.

Let's knock this out.

35. The unit of pressure is the Pascal. B. Pascal

36. A scalar quantity has magnitude only, while a vector quantity has both magnitude and direction. Work is a scalar quantity. C. Work

37. Charles's law states that for a fixed mass of gas at constant pressure, the volume is directly proportional to its absolute temperature. Therefore, as a balloon is heated, its volume expands. A. Charles's law

38. Capillarity, or capillary action, is primarily due to surface tension, which arises from the interplay of cohesive forces within the liquid and adhesive forces between the liquid and the solid surface. A. surface tension

39. A hydrometer is an instrument used to measure the relative density (or specific gravity) of liquids. C. relative density

40. A fluid is defined as a substance that continuously deforms (flows) under an applied shear stress. C. flows easily
