Transverse wave, motion in which all points on a wave oscillate along paths at right angles to the direction of the wave's advance. Surface ripples on water, seismic S (secondary) waves, and electromagnetic (e.g., radio and light) waves are examples of transverse waves.
        
             
        
        
        
Answer:
 199920J
Explanation:
Given parameters: 
Mass of steam  = 85g 
Unknown: 
Heat released when the liquid is condensed  = ? 
Solution: 
The heat released by the substance is given as; 
          H  = mL 
H is the heat released 
m is the mass 
L is the latent heat of steam  = 2352J/g
Heat released  = 85 x 2352  = 199920J
