FIGURE 17-1 -Consider a flat steel plate with a hole through its center as shown in Fig.17-1. When the plate's temperature is decreased, the hole will

Gallium boils at 2205°C. What is the corresponding temperature in the Fahrenheit scale?

If the pressure acting on an ideal gas at constant temperature is tripled, its volume is

State Gay-Lassac's law.

Distinguish between the three phases of matter from the atomic or microscopic point of view.

Convert 14°F to K.

What is the mass density of argon gas at pressure 1.00 × 10⁵ N/m² and at temperature 300 K? The mean atomic mass of argon is 39.948u.

Internal human body temperature is often stated to be normal at 98.6°F. What is this temperature on the Kelvin scale?

A 25-L container holds hydrogen gas at a gauge pressure of 0.25 atm and a temperature of 0°C. What mass of hydrogen is in this container?

A thermometer is made such that the freezing point of water is defined to be 60.0°H and the boiling point of water at sea level is defined to be 520°H. What is absolute zero on the H scale?

The number of molecules in one mole of a substance

The coefficient of linear expansion of lead is 29 × 10^-6K^-1. What change in temperature will cause a 10-m long lead bar to change in length by 3.0 mm?

Express 14°F in °C.

The density of water at 0°C is 999.84 kg/m³ and at 4°C it is 999.96 kg/m³. A 1.0-liter container, full to the brim with water at 4°C is placed in the refrigerator. By the time that the temperature of the water reaches 0°C, how much of the water has spilled from the container, assuming that the contraction of the container is negligible?

An industrial fabrication process stamps out thin metal pieces, each in the shape of a square with a circular hole in the middle, from a large thin sheet. These pieces are mounted in a large machine. As these pieces heat up during regular machine operation, the diameter of the circular hole will

Two metal spheres are made of the same material and have the same diameter, but one is solid and the other is hollow. If their temperature is increased by the same amount,

A machinist needs to remove a tight fitting pin of material A from a hole in a block made of material B. The machinist heats both the pin and and the block to the same high temperature and removes the pin easily. What statement relates the coefficient of thermal expansion of material A to that of material B?

1 L of water at 20°C will occupy what volume at 80°C? Water has a volume expansion coefficient of 210 × 10^-6/C°.

The volume measuring system for a gasoline pump at the service station is calibrated at 20.0°C. If the temperature of the gasoline drops to 10.0°C, what percentage extra amount of mass of gasoline do you receive when making a purchase? The coefficient of volume expansion for gasoline is 9.5 × 10^-4/K.

The volume of a gas is inversely proportional to the absolute pressure applied to it when the temperature is kept constant.
