An electric stove, electric cooker or electric range is a stove with an integrated electrical heating device to cook and bake. Electric stoves became popular as replacements for solid-fuel (wood or coal) stoves which required more labor to operate and maintain.

The electric stove was showcased at the Chicago World's Fair in 1893, where an electrified model kitchen was shown. Unlike the gas stove, the electrical stove was slow to catch on, partly due to the unfamiliar technology, and the need for cities and towns to be electrified.

The first handheld hairdryer appeared on the market in 1925. It produced only 100 watts of heat and therefore did not have sufficient power to dry hair quickly. It weighed over 2 lb (1 kg) because it was made of heavy steel and zinc. Over the next 20 years engineers improved the design and managed to triple the heat output, raising it to 300 watts. By the 1960s, further improvements in electrical technology allowed the production of hairdryers with up to 500 watts of power.

One of the key factors to consider when designing a portable hairdryer is the amount of heating power it can produce. Since warm air is capable of absorbing more moisture than cold air, the temperature of the airflow is critical. By calculating the specific heat of the air and understanding the maximum temperature that can be used without burning the skin, engineers can calculate the amount of power required for the heating element. This ensures that the device will generate enough heat to dry the hair quickly.

From the text above, how can engineers calculate the amount of power needed for a heating element?

• by calculating the specific heat of the heat and understanding the maximum temperature that can be used without burning the skin

• by calculating the specific heat of the moisture and understanding the maximum temperature that can be used without burning the skin

• by calculating the specific heat of the air and understanding the minimum temperature that can be used without burning the skin
