Explanation

(a) The boiling point of a liquid is the temperature at which its s.v.p is equal to the external atmospheric pressure.

(b) Experiment to determine the boiling point of a small quantity of a liquid.

Some liquid is introduced into the shorter length of the J - tube above the mercury. The beaker and its contents are heated and stirred continuously. At a stage when the levels of mercury in the two limbs of the J - tube are the same the temperature is read. At this temperature the s.v.p. of the liquid is equal to the atmospheric pressure. This temperature is the boiling point of the liquid.

(c) Heat lost by copper = Heat gained by water

\(mc \theta = m_{1} c_{1} \theta_{1} + ml\)

\(0.3 \times 400 \times (950° - 100°) = 0.25 \times 4200 \times (100° - 25°) + 2.26 \times 10^{6} M\)

\(M = \frac{102000 - 78750}{2.26 \times 10^{6}}\)

\(M = 10.3g\)

Therefore, the mass of water that will boil away is 10.3g.

(d) Four effects of heat other than expansion are:

(1) Change of state (2) Change in temperature (3) Chemical change (4) Change in electrical resistance of conductivity. (5) Melting sublimation.

Correct Answer: B. Ibadan-Benin-Port Harcourt region

Correct Answer: D) name all the creatures

Explanation

The question is asking about what man was permitted to do in the Biblical account of creation. The options are: A) plant fruit trees for food, B) water the garden, C) make garment of hides and skin, and D) name all the creatures. The correct answer is D) name all the creatures.

According to the Bible, in the account of creation, God created man and gave him the responsibility to name all the creatures that He had created. This is found in Genesis 2:19-20 which says, Now the Lord God had formed out of the ground all the wild animals and all the birds in the sky. He brought them to the man to see what he would name them; and whatever the man called each living creature, that was its name. So the man gave names to all the livestock, the birds in the sky and all the wild animals.

Therefore, the correct option is D) name all the creatures. This shows that man was given an important role in taking care of God's creation and giving names to the animals that God had created.

Correct Answer: C. sincere in all their transactions

Explanation

King Josiah gave the reason that the workers in charge of the renovation should not render an account to anybody because they were sincere in their transactions. This can be found in 2 Kings 22:5-7 (RSV): 5 and let it be given into the hand of the workmen who have the oversight of the house of the Lord; and let them give it to the workmen who are at the house of the Lord, repairing the house, 6 that is, to the carpenters, and to the builders, and to the masons, as well as for buying timber and quarried stone to repair the house. 7 But no accounting shall be asked from them for the money which is delivered into their hand, for they deal honestly.

Explanation

(a) At the beginning of the reign of king Solomon, God asked him to make a request from Him and he rightly asked for wisdom to rule his people well. God added unto him riches and prosperity with the proviso that should he remain loyal like his father, He would grant him long life. Between the two harlots, he exhibited true wisdom in his judgement and he was also famous for his many proverbs and songs and for his botanical and scientific knowledge. The hallmark of his wisdom was, however, the temple which he built for the Lord in Jerusalem. He dedicated it with singing, dancing and sacrifices to the Lord. During the dedication, he prayed to God with devotion, not only for his people, but also for foreigners who would pray to God of Israel while facing the temple in Jerusalem. He brought the ark of the covenant from its former modest place of abode into the very presence of God in the holiest part of the temple. His commercial interests brought prosperity to his country.

(b) Some of king Solomon's unwise decisions are:

(i) Solomon's love of many foreign women was in total negation of God's command.

(ii) He allowed his foreign wives to come into Israel with their foreign gods. Not only did he build temples for these gods, he worshipped them together with these wives of his.

(iii) Solomon's forced labour (made up chiefly of slaves) and his over-taxation dissipated the economy of Israel.

(iv) His foreign diplomatic trading connections often cost Israel loss of territory. (For example, he lost twenty cities to Hiram, king of Tyre which he exchanged for the timber and expertise from Tyre

Correct Answer: A. x² + 5x + 6

Correct Answer: A) man possessed of demons

Explanation

This question is asking about a healing performed by Jesus in the country of the Gerasenes. The question lists four options, and we are to choose the correct one. The correct option is Option A: man possessed of demons.

The story of the man possessed by demons can be found in the Bible, specifically in the book of Mark, chapter 5, verses 1-20. In this story, Jesus and his disciples arrive in the country of the Gerasenes, where they are met by a man possessed by demons. The man lived in tombs and could not be kept under control by anyone. Jesus commanded the demons to leave the man and enter a herd of pigs, which then ran down a steep bank into the sea and drowned. The man was healed and in his right mind.

As Christians, we can learn from this story that we should trust in Jesus' power to heal us and to help us overcome any challenges we may face in life.

In summary, the correct answer to this question is Option A: man possessed of demons. This story shows Jesus' power and compassion and teaches us to trust in him during difficult times.
