The height of the Washington Monument is measured to be 170.00 m on a day when the temperature is .
What will its height be on a day when the temperature falls to ? Assume that the monument’s coefficient of thermal expansion is .
You are looking to buy a small piece of land in Hong Kong. The price is only per square meter. The land title says the dimensions are 20 m by 30 m. By how much would the total price change if you measured the parcel with a steel tape measure on a day when the temperature was above the temperature that the tape measure was designed for? The dimensions of the land do not change. The coefficient of thermal expansion of steel is .
A volume of mercury is contained in a tall, thin, cylinder. The mercury fills the cylinder to a height of 3.0 cm and is at a temperature of . If the mercury is heated to a temperature of , how much does the height of the column of mercury increase? Use a value of for the linear coefficient of expansion of mercury.
