Inorganic type of core binders is generally preferred as compared to organic core binders in core making procedure.

Inorganic type of core binders is generally preferred as compared to organic core binders in core making procedure. Correct Answer False

In general, the binders are present as inorganic as well as organic ones, but for the core making process, organic binders are normally preferred because they are combustible and can be easily destroyed by the heat at high temperatures thereby providing the sufficient collapsibility to the core sand.

By studying all following options, select a pair that uses most closely similar reasoning. a. Researchers have looked at the communication between different animals and found that meerkats have a series of alerts and calls that fail into two categories, greetings and alarms. Since we can be sure that this meerkat is not calling as a greeting, we must accept that he is attempting to raise the alarm. b. Farmers must choose between using organic or non-organic fertilisers on their land. Organic fertilisers can produce a lower crop yield and farmers may find it difficult to change to organic methods if they have been using non-organic methods for some time. Farmers should, therefore, consider the longer-term impacts of their decisions. c. Either young persons are getting cleverer each year or examinations are becoming easier for students to pass. Since there is very little evidence from IQ testing and other supposed benchmarks that young persons are more intelligent now than in the past, we must conclude that the examination system is easier for students today than it was in the past. d. Closed wood burning chulhas are a better way to cook your food than open fire chulhas. Closed wood burning chulhas are highly efficient, whereas the open fire of open fire chulhas loses a great deal of heat in the air. More people should, therefore, use closed wood burning chulhas in their homes.
