Final answer:
To find the energy needed to cool a 350 mL can of soda from 20°C to 0°C, we can use the specific heat capacity formula by assuming the soda's mass equal to its volume, resulting in the calculation (350 g)(4.18 J/g°C)(20°C).
Step-by-step explanation:
The question references the amount of energy required to change the temperature of a cold drink, specifically soda. To calculate the energy required to cool a 350 mL can of soda from 20°C to 0°C, we can use the specific heat capacity formula: Q = mcΔT, where Q is the heat energy, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature. Soda is mostly water, and the specific heat capacity of water is approximately 4.18 J/g°C.
First, we need to convert the soda volume to mass. Since 1 mL of water is approximately equivalent to 1 gram, we can assume the soda has a mass of 350 grams. The temperature change (ΔT) is 20°C. The energy required (Q) is therefore: Q = (350 g)(4.18 J/g°C)(20°C) This calculation would give the energy in joules needed to cool the soda to 0°C. As for the Energy Efficiency Ratio (EER), it is used to assess the efficiency of cooling systems but is not directly applicable to this calculation.
