To find the specific heat of the substance in J/kg-K, we can use the formula:
Specific heat (c) = Thermal capacity / (mass x change in temperature)
Given:
Thermal capacity = 8 calories
Mass = 10g
To convert the thermal capacity from calories to joules, we'll use the conversion factor: 1 calorie = 4.184 joules.
Thermal capacity in joules = 8 calories x 4.184 joules/calorie
Now we can substitute these values into the equation:
Specific heat (c) = (Thermal capacity in joules) / (mass x change in temperature)
Specific heat (c) = (8 calories x 4.184 joules/calorie) / (10g x change in temperature)
Specific heat (c) = (33.472 joules) / (10g x change in temperature)
Since the change in temperature is not given, we cannot determine the specific heat with the given information. Therefore, none of the given options (1.3360 and 2.3630) is correct.
To find the specific heat of a substance, we can use the formula:
Specific heat = Thermal capacity / (mass x change in temperature)
Given:
Mass = 10g
Thermal capacity = 8 calories
We need to convert the thermal capacity from calories to joules. Since 1 calorie is equal to 4.184 joules, we can convert it as follows:
Thermal capacity = 8 calories * 4.184 J/calories
Now, we can calculate the specific heat:
Specific heat = (8 calories * 4.184 J/calories) / (10g x change in temperature)
Unfortunately, the question does not provide the change in temperature. Without that information, we cannot calculate the specific heat accurately. Therefore, none of the given options of 1.3360 and 2.3630 are correct.
