Question

How much energy does it take to boil water for pasta? For a one-pound box of pastayou would need four quarts of water, which requires 15.8 kJ of energy for every degreeCelsius (°C) of temperature increase. Your thermometer measures the startingtemperature as 48°F. Water boils at 212°F.a. How many degrees Fahrenheit (°F) must you raise the temperature?b. How many degrees Celsius (°C) must you raise the temperature?c. How much energy is required to heat the f

Answer 1

The thermometer measures the starting temperature as,

`T_1=48^(\circ)F`

The temperature required for the boiling the water is

`T_2=212^(\circ)F`

(a). The temperature requires to boil is,

`\begin{gathered} T=T_2-T_1 \\ T=212-48 \\ T=164\text{ F} \end{gathered}`
