A parallel plate capacitor at 25 C comprises a slab of dielectric of area 104 m and a thickness of 2 mm. Assuming that the relative permittivity is 1200, the temperature coefficient of permittivity is -15 ppm K-1, and the linear expansion coefficient of the dielectric is 12 ppm K-1, calculate the change in the capacitance that occurs with an increase in temperature of 10 C.
