The temperature at which the Celsius and Fahrenheit thermometers agree (to give the same numerical value) is:
1. | \(-40^\circ\) | 2. | \(40^\circ\) |
3. | \(0^\circ\) | 4. | \(50^\circ\) |
The absolute zero temperature on the Fahrenheit scale is (approximately):
1. \(-273^{\circ}\text{F}\)
2. \(-32^{\circ}\text{F}\)
3. \(-460^{\circ}\text{F}\)
4. \(-132^{\circ}\text{F}\)
1. | \(200^\circ \text{C}\) | 2. | \(230^\circ \text{C}\) |
3. | \(250^\circ \text{C}\) | 4. | \(270^\circ \text{C}\) |
Two holes are cut into a metal sheet. The diameters of the two holes are \(d_1\) and \(d_2\) \((d_1>d_2).\) If the temperature of the metal sheet is increased, then which of the following distance increases?
1. | \(d_1\) | 2. | \(d_2\) |
3. | \(AB\) | 4. | All of the above |
1. | \(3.2 \times 10^6~\text{Pa}\) | 2. | \(2.2 \times 10^8~\text{Pa}\) |
3. | \(4.4 \times 10^8~\text{Pa}\) | 4. | \(2.2 \times 10^9~\text{Pa}\) |
1. | \(2\alpha\) | is
2. | \(4\alpha\) | is
3. | \(\alpha\) and \(3\alpha\) | can be any value between
4. | \(2\alpha\) and \(3\alpha\) | can be any value between
1. | \(d\alpha \Delta T\) | will increase by an amount of
2. | will not change |
3. | \(\left ( 2\pi R-d \right )\alpha \Delta T\) | will increase by an amount
4. | will decrease by an amount of \(d\alpha \Delta T\) |
