Final answer:
The specific heat of the substance is 0.55 J/g·ºC.
Step-by-step explanation:
The specific heat of a substance is the amount of heat energy required to raise the temperature of 1 gram of the substance by 1 degree Celsius or 1 Kelvin. To find the specific heat of the substance in this question, we can use the formula:
Specific heat = (Energy absorbed)/(mass x temperature change)
Given that the substance absorbed 275 J of energy, has a mass of 100 g, and the temperature increased by 50 ºC, we can substitute these values into the formula to solve for the specific heat:
Specific heat = (275 J)/(100 g x 50 ºC) = 0.55 J/g·ºC
Therefore, the specific heat of the substance is 0.55 J/g·ºC.
