One way to keep the contents of a garage from becoming too cold on a night when a severe subfreezing temperature is forecast is to put a tub of water in the garage. if the mass of the water is 148 kg and its initial temperature is 22.3°c, how much energy must the water transfer to its surroundings in order to freeze completely?

The energy is transferred to the surroundings from water in order to freeze completely.

Explanation:

Water will transfer to surrounding will come from cooling energy from 22.3°C  to 0°C and then freezing energy is

We know that,

\mathrm{C}_{\mathrm{W}}=4190 \mathrm{J} / \mathrm{kgk}

As per given question,

M = 148 kg

Substitute the values in the above formula,

The energy is transferred to the surroundings from water in order to freeze completely.

dopamine..

"it was found that some people who were taking the drug l-dopa to raise their levels of dopamine were developing schizophrenic-like symptoms supporting research a strength of the dopamine hypothesis is that there are many studies which have shown support for the neurochemical explanation."
