It deteriorates. Definitely more than when you started.
Heat energy is calculated by multiplying the mass, specific heat capacity of a substance by the change in temperatures. Therefore,the heat lost by water will be given by mass of water (in kg) × specific heat capacity of water × change in temperature. This heat will be equivalent to the heat gained by the spoon calculated by mass of the spoon by specific heat capacity by change in temperature. (considering that the specific heat capacity of gold is 125.6 J/kg/k)
hence, 0.05 kg × 49 × 125.6 J/kg/k = 307.72 Joules
therefore, heat lost by water is equivalent to 307.72 Joules
Answer:
i think it's either A or D.
Answer:
Electrolytes are observed by conductivity - so unknown 2 should be circled, and Tap Water, which almost always contains electrolytes, mineral salts in solution.
Explanation:
The answer is lead.
