It Is Necessary to Determine the Specific Heat of an Unknown

question 50

Multiple Choice

It is necessary to determine the specific heat of an unknown object. The mass of the object is 201.0 g. It is determined experimentally that it takes 15.0 J to raise the temperature $10.0 ^ { \circ } \mathrm { C }$ What isthe specific heat of the object?

• A) \(0.00130 \mathrm {~J} / \mathrm { kg } \cdot \mathrm { K }\)
• B) \(7.46 \mathrm {~J} / \mathrm { kg } \cdot \mathrm { K }\)
• C) \(3,020,000 \mathrm {~J} / \mathrm { kg } \cdot \mathrm { K }\)
• D) \(1500 \mathrm {~J} / \mathrm { kg } \cdot \mathrm { K }\)
