61. On impulse, he reached out and passed his hand through the vapour.

62. The inert gas argon is added to help to start the discharge because the vapour pressure of the mercury is very low.

63. Snow crystals form when atmospheric conditions turn water vapour into ice.

64. The liquid is turned into a vapour and the pressure of the expanding vapour turns a turbine to produce the electricity.

65. The only option may be a single mercury vapour or metal halide spotlight(sentencedict.com), with no option for extra support lighting.

66. The more volatile component is the one whose molecules have a greater tendency to escape into the vapour phase.

67. Any decline in water loss might also be partly offset by the resulting increase in atmospheric water vapour pressure deficit.

68. The increase in vapour pressure with temperature can be explained in terms of the kinetic theory.

69. The amount of water vapour in a battery depends on the concentration of sulphuric acid in the solution.

70. Water vapour is a naturally occurring greenhouse gas but the amount of water vapour in the atmosphere is affected by human activities.

71. Otherwise, impact scattering and condensation from impact vapour must be responsible for this uniformity.

72. The benzine leaked and this caused the ship's hold to fill with vapour.

73. Thus, at various stages in the column the descending liquid and the ascending vapour are in equilibrium.

74. Such gases, mixed with water vapour, were subjected to electrical discharge and ultraviolet light.

75. In other words the vapour and liquid forms of water are indistinguishable above this point.

76. The vapour might condense and fall on the slopes as a new sort of lubricant snow.

77. Profiled insulation panels are laid on top of vapour barrier and then covered with Rockwell sheet.sentencedict .com

78. These were sealed in the same way as the rooflights, with air / vapour barrier material and plenty of butyl tape.

79. High overhead, a jet laid its vapour trail across a bleached-blue sky.

80. A vapour barrier is formed by packaging the salt in foil lined boxes.

81. Ruth flopped back in the lounger and studied the vapour trail through half-closed eyes.

82. On the Earth there is regularly more evaporation - effusions of water vapour from the surface - by day than by night.

83. It was here that the rising air from the plain turned to vapour and formed the miraculous halo.

84. The top line is a plot of vapour pressure of the liquid mixture against liquid composition.

85. It was inflated with liquid rubber monomer under its own vapour pressure.

86. In its place, service stations were to be required to install vapour traps directly on to petrol pumps.

87. When temperature is increased, the partial pressures of both components and the total vapour pressure of the mixture increase.

88. A mixture which exerts a vapour pressure greater than that predicted by Raoult's law is said to show a positive deviation.

89. The vapour of his breath feathered in a trail behind him as he moved through the cold bushes towards the stream.

90. The more volatile component is thus the one with the higher vapour pressure.
