Correct Answer: A) primary securities market

Explanation

On the other hand, the secondary securities market, mentioned in Option B, is where already issued securities are traded among investors. This includes stock exchanges where investors can buy and sell shares of publicly traded companies.

Options C and D, first-tier and second-tier securities markets, are not commonly used terms in the context of IPOs. It's important to focus on the primary securities market as the correct answer.

To summarize, an initial public offering (IPO) is undertaken through the primary securities market, where new securities are issued and sold to the public for the first time. This allows companies to raise capital and investors to become shareholders in the company.

Correct Answer: D. was in control

Correct Answer: D. Violence

Explanation

(a) Heat capacity is the quantity of heat required to change the temperature of a body by 1K. The unit is JK\(^{-1}\)

(b) Effects of heat on a substance are:

(i) Increase in temperature.

(ii) Change of state.

(iii) Change in colour .

(iv) Change in electrical resistance, etc.

(c) To remove a tightly fitted glass cork from a reagent bottle, warm the bottle neck using warm cloth to make the glass bottle to expand creating space for easy removal of the cork.

(d)(i) Pt = MC\(\Delta \theta\)

\(\Delta \theta = \frac{pt}{Mc} = \frac{1200 \times 3 \times 60}{0.8 \times 4000}\) =67.5°

= final temp \(\theta\) = 67.5 + 30° = 97.5°C

(ii) Containers with tight-fitted lids are not suitable because with increase in temperature the steam molecules from the container are confined in the container, thereby increasing the rate of collission of the steam with the walls of the container, hence in pressure inside the container. Thus the high pressure can burst the tightly-fitted container and the hot content released.

(iii) The observed dent on the container is due to the condensation of the steam in the container which-will lead to a decrease in pressure in the greater container making the atmospheric pressure greater than the pressure in the container.
