Consider the following statements 1. Dry ice is the solid form of CO2. 2. Dry ice is used primarily as a cooling agent. 3. Water ice is colder than dry ice. Which of the statement(s) given above is/are correct? A. Only 1 B. Only 2 C. 1 and 2 D. 1, 2 and 3

The correct answer is C. 1 and 2.

Dry ice is the solid form of carbon dioxide. It is used primarily as a cooling agent because it sublimates (turns directly from a solid to a gas) at -78.5 degrees Celsius, which is much colder than water ice. Water ice melts at 0 degrees Celsius.

Therefore, statements 1 and 2 are correct. Statement 3 is incorrect because dry ice is colder than water ice.
