The charge stored in a parallel plate capacitor is proportional to the _____(potential, current) and across _____ (resistance, c
Aleksandr-060686 [28]

Answer:

The charge stored in a parallel plate capacitor is proportional to the potential, and capacitance across the plates.

Explanation:

The capacitance of a parallel plate capacitor is given by:

C=\frac{Q}{V}

where

Q is the charge stored

V is the potential difference across the capacitor

Re-arranging the formula, we get

Q=CV

From this expression, we see that the charge stored (Q) is proportional to both the potential (V) and the capacitance (C).

How much heat (in kJ) is needed to convert 866 g of ice at −10°C to steam at 126°C? (The specific heats of ice and steam are 2.0
elena-14-01-66 [18.8K]

Answer:

2671.3 kJ

Explanation:

m = 866 g at - 10 degree C converts into steam at 126 degree C.

The following steps are there

(1) ice at - 10 degree C converts into ice at 0 degree C

H1 = m x specific heat of ice x ΔT

H1 = 866 x 2.03 x 10 = 17579.8 J

(ii) ice at 0 degree C converts into water at 0 degree C

H2 = m x Latent heat of fusion = 866 x 334 = 289244 J

(iii) water at 0 degree C converts into water at 100 degree C

H3 =  m x specific heat of water x ΔT

ΔH3 = 866 x 4.186 x 100 = 362507.6 J

(iv) water at 100 degree C converts into steam at 100 degree C

H4 = m x Lateant heat of vaporisation

H4 = 866 x 2260 = 1957160 J

(v) seam at 100 degree C converts into steam at 126 degree C

H5 = m x specific heat of steam x ΔT

H5 = 866 x 1.99 x 26 = 44806.84 J

The total heat required is

H = H1 + H2 + H3 + H4 + H5

H = 2671298.24 J = 2671.3 kJ
