21. They take up heat from X 2 : this gives the desired cooling effect . 22. Evaporation of water through the permeable exoskeleton may, however, provide a valuable cooling effect . 23. As the hydrates are spent, water vapour is released, which has a cooling effect . 24. Many skateboarding dogs appear to enjoy the cooling effect of the wind on their tongues. 25. This evaporation has a cooling effect due to the latent heat of evaporation of water. 26. The peninsula, which lies outside the wind vortex, escapes the cooling effect , the scientists said. 27. These aerosols can cause a cooling effect on earth. 28. Evaporation of sweat from the skin surface has a cooling effect due to evaporative cooling. 29. This would tend to counteract the cooling effect of lighter, liquid aerosols that reflect sunlight. 30. The uncombusted fuel expelled out the exhaust also takes heat with it, providing the cooling effect .
