15) 650. J is the same amount of energy as _<\/strong> A) 155 cal B) 2720 cal C) 650. cal D) 1550 cal E) 2.72 cal<\/p>\n\n\n\n

The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n

To convert joules (J) to calories (cal), we use the conversion factor: 1\u2009J=0.239\u2009cal1 \\, \\text{J} = 0.239 \\, \\text{cal}1J=0.239cal<\/p>\n\n\n\n

Given that you have 650 J, the conversion would be: 650\u2009J\u00d70.239\u2009cal\/J=155.35\u2009cal650 \\, \\text{J} \\times 0.239 \\, \\text{cal\/J} = 155.35 \\, \\text{cal}650J\u00d70.239cal\/J=155.35cal<\/p>\n\n\n\n

So, the closest answer would be A) 155 cal<\/strong>.<\/p>\n\n\n\n

Explanation:<\/h3>\n\n\n\n

The conversion factor between joules and calories comes from the definition of a calorie as the amount of energy required to raise the temperature of 1 gram of water by 1\u00b0C. The energy in joules is a more standard SI unit used for measuring energy, while calories are often used in food energy and thermodynamics.<\/p>\n\n\n\n

This conversion is crucial in various scientific and practical fields, such as physics, chemistry, and nutrition, where both joules and calories are used to quantify energy.<\/p>\n\n\n\n
