To sterilize a 53.0 g glass baby bottle, we must raise its temperature from 25.0°c to 92.0°c. how much heat transfer (in j) is required?

The heat transferred is, Q = 2982.84 J

Explanation:

Given data,

The mass of the glass bottle, m = 53 g

                                                     = 0.053 kg

The change on temperature, ΔT = T² - T₁

                                                       = 92 - 25

                                                       = 67 ° C

The formula for heat transfer is,

                                 Q = mcΔT

Where,

                            c - specific heat capacity of the material

Substituting the values

                             Q = 0.053 x 840 x 67

                                 = 2982.84 J

Hence, the heat transferred is, Q = 2982.84 J

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
