Perform each conversion.

(a) 588 cal to joules

(b) 17.4 J to Calories

(c) 134 kJ to Calories

(d) 56.2 Cal to joules

Solution 51P

Here, we are going to convert the unit from Cal to joule or Joule to cal.

(a)588 cal to joules

We know,

1 Cal = 4.1868 Joule

Therefore, the conversion factor =

Thus,

588 cal x = 2461.8384 Joule

= 2.46 kJoule.

Therefore,

588 cal = 2.46 kJ

(b) 17.4 J to Calories

We know,

1 Cal = 4.1868 Joule

Therefore, the conversion factor =

Thus,

17.4 J x = 4.156 cal

Therefore,

17.4 J = 4.156 cal

(c) 134 kJ to Calories

We know,

1 Cal = 4.1868 Joule

1 000 J = 1 kJ

Therefore, the conversion factor = ,

Thus,

134 kJ x x = 32005.3 cal

Therefor

134 kJ = 32005.3 calories = 32.0 kilocalories

(d) 56.2 Cal to joules

We know,

1 Cal = 4.1868 Joule

Therefore, the conversion factor =

Thus,

56.2 cal x = 235.29 Joule

= 0.2353 kJ

Therefore,

56.2 cal = 0.2353 kJ
