71.   Not only does this result in a more palatable food but the extrusion process makes the food more digestable and therefore more nutritious.

72.   For most chemical reactions the rate of reaction is much slower than the collision frequency so you must assume only a small fraction of collisions result in a reaction.

73.   From the results in Conn and Lee we see that subjects more accurately recognised trigrams presented on a card when the material is presented to the left hemisphere.

74.   Aspects of both the suggested hypotheses were supported as each showed a result in its favour and thus the exact mechanism for adaptation was not determined.

75.   Thus each procedure call results in a new set of registers allocated for use by that new procedure.

76.   Describe briefly an experiment that could be carried out to obtain these results in the laboratory.

77.   We saw above that the work done by a chemical system frequently results in expansion.

78.   A change in phase-melting, vaporisation or sublimation, for example-always results in an enthalpy change.

79.   On the other hand, the accumulation of dust in the upper atmosphere results in cooling since the solar radiation is reflected away from the Earth.

80.   Fractional distillation results in pure B and a mixture having the composition X.
