Graham's law says effusion rate goes as one over the square root of molar mass, so helium, at 4 g\/mol, escapes about 2.6 times faster than nitrogen at 28 g\/mol. Helium balloons go flat quickly. Pixel-art kiss-cut sticker in 2, 3, 4 and 6 inches; equation, symbols and sources in the physics panel below.\u003c\/p\u003e","brand":"Printify","offers":[{"title":"2\" × 2\" \/ White","offer_id":50658296201319,"sku":"16508068807966341441","price":4.99,"currency_code":"USD","in_stock":true},{"title":"3\" × 3\" \/ White","offer_id":50658296234087,"sku":"33330399263211933753","price":6.99,"currency_code":"USD","in_stock":true},{"title":"4\" × 4\" \/ White","offer_id":50658296266855,"sku":"33793830177386223732","price":8.99,"currency_code":"USD","in_stock":true},{"title":"6\" × 6\" \/ White","offer_id":50658296299623,"sku":"22907736018781491988","price":11.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0596\/8746\/9159\/files\/01_clean_779aa16b-016d-4ea8-b2e9-01900db9fb74.jpg?v=1792798503","url":"https:\/\/pixelatedphysics.com\/products\/seepix-grahams-law-pixel-sticker","provider":"Pixelated Physics","version":"1.0","type":"link"}
