S Astronomers think that Mercury's scarps formed as the planet's diameter shrank by about 5 km. (Enter your answers to three significant figures.) a. If the 3600-km diameter core actually shrank by 5.9 km, by what percentage did Mercury's volume decrease? % b. If the volume of iron changes by about 30 parts per million for each Kelvin of temperature change, by how much would the core's temperature have had to change? K
