Diethyl ether freezing point
WebDiethyl ether, a substance once used as a general anesthetic, has a specific heat of 0.895 cal/goC. How many calories of heat are needed to raise the temperature of 30.0 g of diethyl ether from 10.0 oC to 30.0 oC? Heat = specific heat x mass x delta t Heat = ( 0.895 cal/goC) x 30.0 g x 20.0 oC = 537 cal WebOct 4, 2024 · That means that at room temperature, dimethyl ether is a gas, because it is above its boiling point.
