If a 13.9 g object has a specific heat of 1.31J/g ∘ C and it experiences a temperature increase from 55.0 ∘ C to 67.5 ∘ C , how much heat in joules did it absorb?
The heat capacity of an object is given by the following equation What is the change in the entropy of the object (in J associated with raising its temperature from 290 K to 380 K?
The temperature of an object increases by 48.3 °C when it absorbs 3701 J of heat. Calculate the heat capacity of the object. C = 0.240 The mass of the object is 319 g. Use the table of specific heat values to identify the composition of the object. Substance gold silver Specific heat (J/(g · °C)) 0.129 0.240 0.444 0.900 iron aluminum
Specific Heat (more precise) The heat capacity of an object indicates how much energy that object can absorb for a given increase in that object's temparature. In a system in which two objects of different temperatures come into contact with one another, the warmer object will cool and the cooler object will warm up until the system is at a single equilibrium temperature. Note the difference between the terms molar heat capacity, which has units of J/mol- Degree C, and...
An object absorbs 1.70×104J of heat and as a result, its temperature is increases from 45.0∘C to 75.0∘C. What is its heat capacity of the object?
A) If 24.67 grams of water showed a temperature increase of 0.85 °C, what is the heat change for the water in joules? The specific heat capacity of water is 4.184 J/(g⋅°C).
