Answer
Converting 53 degree C to Fahrenheit
{53*(9/5)} +32 = 127.4 Fahrenheit
now converting 53 degree C in Kelvin
53+273.15= 326.15 K

- A student is trying to identify an unknown solid based on its melting point. She noted that the compound began to melt at 182°C and finished melting at 187°C. Knowing it is possible for there to be impurities in the sample, is this compound more likely to be camphor or hydroquinone. Explain your reasoning. A young chemist has synthesized what he believed to be acetaminophen. He measured the melting point of this newly formed compound to be 163-178°C. If...

An unknown material has a normal melting/freezing point of -29.9 °C, and the liquid phase has a specific heat capacity of 164 J/(kg C°). One-tenth of a kilogram of the solid at -29.9 °C is put into a 0.100-kg aluminum calorimeter cup that contains 0.105 kg of glycerin. The temperature of the cup and the glycerin is initially 27.3 °C. All the unknown material melts, and the final temperature at equilibrium is 18.4 °C. The calorimeter neither loses energy to...
